I-Selersese EtherNgaba i-polymer ye-nonic ye-ionic ye-unic ye-unic ye-unic ye-unic ye-unicremetic, enganyibilikisi kwaye inyibilikisiwe. Ineziphumo ezahlukeneyo kumashishini ahlukeneyo. Umzekelo, kwizinto zokwakha iikhemikhali, ineziphumo ezihlanganisiweyo zekhemikhali: ① Arhente yokuGcina amanzi kwishishini le-polyvinyl pherviny, sisimo esouressifier kwaye sisasazeke; Kumzi-mveliso wamachiza, yindawo ye-Binder kunye ne-Ageffmer Agement ikhuphe izixhobo ze-skeleton, njl. Okulandelayo, ndiza kugxila ekusetyenzisweni kunye nomsebenzi we-seluplose ether kwizinto zokwakha izibonelelo zokusindisa.
1. Kwipeyinti ye-Latex
Kwimveliso yepeyinti ye-Fetex, i-HydroxyEtheetheetheethy kufuneka ikhethwe. Ukucaciswa ngokubanzi kwe-viscofity yiRT30000-500000000, kwaye i-dosage yesalathiso ngokubanzi malunga ne-1.5 ‰ -2 ‰. Owona msebenzi ophambili we-hydroxyythl kwipeyinti ye-Latex yeyokuthintela i-pigment, thintele i-pigment ye-pigment, nceda ukusasazeka, i-Latex, kunye nokuzinza kwecandelo, kwaye kuluncedo ekusebenzeni kwenqanaba lolwakhiwo: I-HydroxyEtheetheethy Ethym sellyulose ilula ukuyisebenzisa. Ingachithwa kumanzi abandayo kunye namanzi ashushu, kwaye ayichaphazeleki kwixabiso le-pH. Ingasetyenziswa phakathi kwexabiso le-2 ne-12. Zintathu iindlela zokusetyenziswa:
I. Yongeza ngqo kwimveliso:
Le ndlela kufuneka inyule i-hydroxythl seluplose Amanyathelo alandelayo: Kude kufike zonke izixhobo ze-gronadd ezinzwayo kunye nezixhobo ezisisiseko, njl.
Ⅱ. Ixhotywe ngotywala bukamama ukuze isetyenziswe kamva:
Le ndlela inokukhetha uhlobo lwethutyana, kwaye inesiphumo se-anti-myupew yeseluplose. Inzuzo yale ndlela kukuba iguquguqukele ngakumbi kwaye inokutongelwa ngokuthe ngqo kwipeyinti ye-Latex. Indlela yokulungiselela iyafana namanyathelo ①-④.
Ⅲ. Luyilungiselele kwi-porridge yokusetyenziswa kamva:
Kuba izinyibilikisi ze-organic zingamaxesha amaninzi 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.
I-2. Kwi-Dall Skrack
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-putty, i-hydroxypropyl methylcelcelculose ikhethiwe ngokubanzi, kwaye ukuguquguquka kwe-viscofity yi-80 000-90,000. Indima yindawo yokugcina amanzi, i-bonding, i-bybrications njalo njalo.
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-3 ‰ -5 ‰.
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.
I-3. Ikhonkrithi yekhonkrithi
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. Inkunkuma yezixhobo kunye nokusebenza okungahambelaniyo. Isitshixo kukuba amanzi aphezulu, kwaye i-hydration yangaphakathi ingaphelelanga. Ke ngoko, isisombululo sale ngxaki kukongeza i-Hydroxypropyl Methylcelcelcelose phakathi kwe-150,000 ne-200,000 kwisibelekazi. , isixa esongezelelekileyo simalunga ne-2 ‰ -3 ‰, kunye nexabiso lokugcina amanzi linganyuka lingaphezulu kwe-92%. Indlela yokusetyenziswa kwikhonkrithi ye-durr yekhonkrithi kukongeza amanzi emva komgubo owomileyo uxutywe.
I-4. Kwi-pypsul Gypsum, i-Bypsum yeGypsum, i-gulking gypsum
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 ugudileyo, akathobeli umgubo, ubotshwe ngokuqinileyo kwisiseko, akasebenzi, kwaye awile, kwaye awile, kwaye awile, kwaye awile, kwaye awile, kwaye uwile, kwaye uwile, kwaye unomsebenzi we-rooffrofprofrofprofrofprofroff; I-Bypsim ebomvu luhlobo olutsha lwebhodi yokukhanya yeBhodi yeBhodi yeBhodi yinto enamathelayo eyenziwe nge-gypsum njengezinto ezisisiseko kwaye zongeze izongezo ezahlukeneyo. Ilungele ukoyikwa phakathi kwezinto ezahlukeneyo zodonga. Ayisiyo inetyhefu, ingenaxabiso, amanqaku anje ngamandla angaphambili, ukuseta ngokukhawuleza, kunye nokugxeka ngokuqinileyo, yinto exhasayo yokwakha iiphaneli kunye nolwakhiwo lwebhlokhi; Iarhente ye-Gyppum ye-Gyppum ngumsinga ongumqadi phakathi kwe-gypsim panels kunye ne-filler yokulungisa iindonga 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. Kungenxa yokuba i-Gypsum yahlulwe yaba yiGypsum yeGyDusm kunye neGypsum eyahlukileyo, i-gypsum eyahlukileyo ineziphumo ezahlukeneyo ekusebenzeni kwemveliso, ke i-fucketion, ukugcinwa kwamanzi, ukugcinwa kwamanzi nokulungisa umgangatho wezinto zokwakha zeGyppum. 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. -60000, isixa esongezelelekileyo siphakathi kwe-1.5 ‰ -2 ‰, kwaye i-selsulose igxile ekugcinweni kwamanzi kunye nokubuyisa i-tybhuysetion.
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.
I-5. Ukufakwa kwe-thermal
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-viscofity ephezulu (malunga ne-150,000), idosi ngokubanzi phakathi kwe-2 ‰ -3 ‰), kwaye indlela yokusetyenziswa ngumgubo owomileyo.
I-6. Iarhente yokujonga
Iarhente ye-Agement kufuneka ibe yi-HPNC20000, kunye ne-TIle Adhestive zinokuba ngaphezulu kwe-100,000. Iarhente yearhente kufuneka isetyenziswe njenge-thi chuoker, enokuphucula amandla amanye kunye namandla anqabileyo.
