I-selsulose ether yi-unic synthetic yemolekyuli ephezulu yemolekyuli, ejijelwe ngamanzi kwaye inyibilikisiwe. Ineziphumo ezahlukeneyo kumashishini ahlukeneyo. Umzekelo, kwizinto zokwakha iikhemikhali, ineziphumo ezihlanganisiweyo zilandelayo:
I-①water igcina iarhente yearhente ②thickener
Kwishishini le-polyvinyl pherviny, sisimo esouressifier kwaye sisasazeke; Kumzi-mveliso wamachiza, yindawo yokubhabha kunye ne-Spof Stores, ilawulwa, njl njl. Oku kulandelayo kugxilwe kusetyenziso kunye nomsebenzi we-seluplose ither kwizinto ezahlukeneyo zokwakha.
(1) kwipeyinti ye-Latex:
Kwishishini lepeyinti ye-Fetex, ukukhetha i-hydroxyEsethl sellulose, inkcazo ngokubanzi ye-viscofity elinganayo yi-RT30000-5000cPs, ehambelana ne-HBB250CEP, ehambelana ne-HORYCE ngokubanzi malunga ne-1.5 ‰ -2 ‰. Owona msebenzi ophambili we-hydroxyythl kwipeyinti ye-Latex yeyokuthintela i-pigment, thintele ukusasazeka kwe-pigment, uzinzo lwe-fastx, kunye nokwandisa ukumiliselwa kwenqanaba lolwakhiwo: I-HydroxyEtheetheetheetheetheetheetheetheetheetheetheetese ilula ukuyisebenzisa. Ingachithwa kumanzi abandayo kunye namanzi ashushu, kwaye ayichaphazeleki kwixabiso le-pH. Ingasetyenziswa ngokukhuselekileyo phakathi kwexabiso le-PI 2 ne-12. Iindlela zokusetyenziswa yile ilandelayo:
I. Yongeza ngokuthe ngqo kwimveliso: Le ndlela kufuneka inyule i-hydroxythyl seluplose yohlobo oluthile, kunye ne-hydroxytethl seluplose enexesha lokuchitha ixesha elingaphezulu kwemizuzu engama-30, amanyathelo ayo asebenzisayo alandelayo:
①POPAR Ixabiso lobungakanani lamanzi aphumeleleyo kwisitya esine-agitar ephezulu ye-Shear
②Start ukuphakamisa ngokuqhubekayo kwisantya esisezantsi, kwaye kwangaxeshanye ngokuthe ngcembe wongeza i-hydroxyytethl kwisisombululo ngokulinganayo
I-③continunue ukufunxa kude kube zonke izinto ezinemigram zifakwe
Yongeza ezinye izicelo zongezwa kunye neziseko ezisisiseko, njl.
⑤ Sult de the onke amaqela e-hydroxyyl achithwe ngokupheleleyo, emva koko wongeza amanye amacandelo kwifomula, kunye nokugaya kude kube yimveliso egqityiweyo.
Ⅱ. Ixhotywe ngotywala bukamama ukuba isetyenziswe kamva: Le ndlela inokukhetha i-seluplose yethutyana, enefuthe lokuphononongwa. Inzuzo yale ndlela kukuba iguquguqukele ngakumbi kwaye inokutongelwa ngokuthe ngqo kwipeyinti ye-Latex. Indlela yokulungiselela iyafana namanyathelo ①-④.
Ⅲ. Lungiselela i-Porridge yokusetyenziswa kamva: Ekubeni izinyibilikisi zendalo zizinto ezinqabileyo (i-insullen) ye-hydroxyyteythl, ezi zinyibilikisi zinokusetyenziselwa ukulungisa i-porridge. Ezona zigqibo zisetyenziswayo zisetyenziswayo zisetyenziswayo zizinto eziphilayo ze-organic kwindawo yokupeyinta i-FEELX, ezinje nge-ithylene glycol, i-propylene glycol, kunye neearhente zefilimu (ezinjengee-dizylene glyl suttate). I-Porridge ye-Holdroxythyl isellise inokulongezwa ngokuthe ngqo kwipeyinti. Qhubeka nokuvuselela kude kukhanyeswe ngokupheleleyo.
(2) Kwi-Dolop Skutty:
Okwangoku, kwizixeko ezininzi kwilizwe lam, indawo yokunganyangekiyo kunye nokunganyangeki kwendawo enganyangekiyo ixabiswe ngabantu. Iveliswa yimpendulo ye-acetal ye-vinyl utywala kunye ne-formaldehydehyde. Ke ngoko, le nto ishenxiswa ngabantu, kwaye i-Sersuse Ether Erise Series isetyenziselwa ukutshintsha olu phawu. Oko kukuthi, ukuphuculwa kwezinto zokwakha ezinobuhlobo bokusingqongileyo, i-sellyuese okwangoku kuphela kwezinto.
Kwindlela enganyangekiyo yamanzi, yahlulwe yangamacala amabini: i-powder eyomileyo ayinamathisi. Phakathi kwezi ntlobo zimbini ze-ifatty, ezilungisiweyo ze-methyl ye-melsulose kunye ne-hydroxypropy ye-methyl kufuneka ikhethwe. I-Viscofity Ingcaciso ngokubanzi phakathi kwe-30000-600cps. Imisebenzi ephambili ye-itlulose e-Ittty yindawo yokugcina amanzi, i-bonds kunye ne-thabrication. Kuba ifomula ye-putty yabavelisi abahlukeneyo zahlukile, ezinye zii-calcium engwevu, i-calcium yokukhanya, isamente emhlophe, njl njl, njl njl. Iifomula ezimbini zahlukile. Isixa esongeziweyo simalunga ne-2 ‰ -3 ‰. Ekwakhiweni kwendlela yokubeka i-wall, kuba umhlaba osisiseko udonga lunomgangatho othile wokufumana amanzi Ukudityaniswa nokuphuma kwehlabathi elingaphandle, ukuba i-DOTTY iphulukana namanzi ngokukhawuleza, iya kukhokelela kwi-rocks okanye i-powder esuswe, ethi ibonakalise amandla ka-Uty. Ke ngoko, ukongeza i-ilesese i-ether kuya kuyisombulula le ngxaki. Kodwa umgangatho we-filler, ngakumbi umgangatho we-Ash Calcium nako kubaluleke kakhulu.
Ngenxa ye-viscosity ephezulu yeselselose, i-Buoyisay ye-ITTY iphuculwe, kwaye i-Shenomen etyhafileyo iphinde yathintelwa, kwaye ikhululekile kakhulu kwaye ikhuselekile ekusebenzeni. Kulungele ukongeza i-seluplose ether kwi-powder itoty. Ukuveliswa kwayo kunye nokusetyenziswa kwayo kulula ngakumbi. I-fililler kunye nezongezo zinokudityaniswa ngokucacileyo kwi-powder eyomileyo.
(3) Umlanjana wekhonkrithi:
Ngombutho wekhonkrithi, ukufezekisa amandla okugqibela, isamente kufuneka ihluleke ngokupheleleyo. Ngakumbi ukwakhiwa kwehlobo, udaka lwekhonkrithi luphulukana namanzi ngokukhawuleza, kwaye amanyathelo o-hydration ogqityiweyo asetyenziselwa ukugcina nokutshiza amanzi. Inkcitho yezixhobo kunye nokusebenza okungahambelaniyo, isitshixo kukuba amanzi aphezulu, kwaye i-hydication yangaphakathi ingaphelelanga, ke isisombululo sale ngxaki kukudibanisa i-Ager-Prion Conserte, khetha i-Hydroxly Godyl okanye i-methyl seluplose, i-viscofity yegama eliphakathi kuka-20000-60000cps, kunye nexabiso elongeziweyo yi-2% -3%. Ireyithi yokugcina amanzi inokunyuswa ngaphezulu kwe-85%. Indlela yokusetyenziswa kwikhonkrithi yekhonkrithi kukudibanisa umgubo owomileyo ngokulinganayo kwaye uthule emanzini.
.
Ngophuhliso olukhawulezileyo lweshishini lokwakha, imfuno yabantu yezinto zokwakha ezitsha ikwanda imihla ngemihla. Ngenxa yokwanda kokwaziswa kwabantu kukhuseleko lwendalo kunye nokuphuculwa okuqhubekayo kokusebenza ngokukuko, iimveliso ze-cemestigual ze-cemestigual ziye zaphuhliswa ngokukhawuleza. Okwangoku, ezona ntlobo ziqhelekileyo ze-gypsum zifihla i-gypsum, i-godpsum ye-godpsum, i-insiid gypsum, kunye ne-tile. Ukupaka i-gypsum yinto ephakathi yokubekwa phantsi kweendonga zangaphakathi kunye nophahla. Umphezulu wodonga uphakanyisiwe kwaye kulungile kwaye kulungile. Ibhodi entsha yokwakha iBhodi yeBhodi yeBhodi ye-Adhengive yindawo enamathele e-Gypsim njengezixhobo ezisisiseko kunye nezixhobo ezahlukeneyo. Ilungele ukoyikwa phakathi kwezinto ezahlukeneyo zodonga. Ayisiyo inetyhefu, amandla e-odor, kwangoko kunye nokumiswa ngokukhawuleza, ukuxhobisa okuqinileyo kunye nezinye iimpawu, zizinto ezixhasayo zokwakha iibhodi zebhlokhi kunye nokwakhiwa kwebhloko; Iarhente ye-Gyppum ye-Gyppum ngumzili we-filler filler phakathi kweebhodi ze-gypsim kunye nokulungisa i-filler yedonga kunye neendonga.
Ezi mveliso ze-gypsim zinothotho lwemisebenzi eyahlukeneyo. Ukongeza kwindima ye-gypsim kunye neefilimu ezinxulumene noko, umba ophambili kukuba i-Seatheritives eyongezelelweyo idlala indima ekhokelayo. Kuba i-gypsum yahlulwe yaba yi-anhydaral gypsum kwaye i-hemimdrate gypsum, i-gypsum eyahlukileyo ineziphumo ezahlukeneyo kwimveliso, i-curing, ukugcinwa kwamanzi, ukugcinwa kwamanzi kunye nokubuyiselwa komhlaba. Ingxaki eqhelekileyo yezi zixhobo ikhutshiwe kwaye ikhwele, kwaye amandla okuqala akanakufikelelwa. Ukusombulula le ngxaki, kukukhetha uhlobo lwesellulose kunye nendlela yokusetyenziswa kwesixhobo sokuhlala. Kule meko, i-methyl okanye i-hydroxypropyl methyl i-30000 inyuliwe. -60000cps, isixa esongezelelweyo yi-1.5% -2%. Phakathi kwawo, I-SellUlose igxile ekugcinweni kwamanzi kunye nokubuyisa i-oyile. Nangona kunjalo, akunakwenzeka ukuba ixhomekeke kwi-ether sether njenge-restarder, kwaye kuyanyanzeleka ukongeza i-cicric rearder ukuxuba kunye nokusetyenziswa ngaphandle kokuchaphazela amandla okuqala.
Ukugcinwa kwamanzi ngokubanzi kubhekisa ukuba amanzi amaninzi azakulahleka ngokwemvelo ngaphandle kokufunxa kwamanzi angaphandle. Ukuba udonga luyomile kakhulu, ukufunxa kwamanzi kunye nokuphuma kwendalo kumphezulu wendalo kuya kwenza ukuba izinto ziphulukane namanzi ngokukhawuleza, kwaye ukuqhekeza kwaye ukonakala kwaye kuyakwenzeka. Le ndlela yokusetyenziswa ixutywe nomgubo owomileyo. Ukuba ulungiselela isisombululo, nceda ujonge kwindlela yokulungiselela yesisombululo.
(5) uHlobo lweThermal
UHlolo lwe-insurser luhlobo olutsha lwezinto ezingaphakathi zokuThintelwa kwingingqi esemantla. Yinto eyenziwe ngodonga olwenziwe sisixhobo sokufakwa, udaka kunye ne-binder. Kule nto, i-seluplose idlala indima ephambili ekwenzeni nasekukhuliseni amandla. Ngokukodwa khetha i-methyl seluplose nge-viscosity ephezulu (malunga ne-10000s), idosi ngokubanzi phakathi kwe-2 ‰ -3 ‰), kwaye indlela yokusetyenziswa ngumgubo owomileyo.
(6) Iarhente ye-interface
Khetha i-HPNnc 20000cps zearhente ye-Agement, khetha i-60000cps okanye ngaphezulu kwi-tile, kwaye ugxile kwi-tickener ene-arhente kwi-arhente yeGrant kunye ne-anti-utolo. Isetyenziswe njengearhente yokugcina amanzi kwi-thayile yokuthintela iithayile kwi-diledy ngokukhawuleza kwaye iwele.
IXESHA LOKUQALA: NgoFebruwari-16 ukuya ku-2003
