I-Teluplose Ether luhlobo lwe-un-ionic ye-unic synthetic yemolekyuli. Ineentlobo ezimbini zeepropathi ezinyibilikayo zamanzi kunye nezinyibilikisi. Ineziphumo ezahlukeneyo kumashishini ahlukeneyo. Umzekelo, kwizinto zokwakha iikhemikhali, ineziphumo ezihlanganisiweyo zekhemikhali: Ukugcina iarhente ye-①wayickener kwishishini le-PVC, ngumkhulu kwaye usasazeke; Kumzi-mveliso wamayeza, yibhanti kwaye ngenxa yokuba i-sellulose ineziphumo ezahlukeneyo ezihlanganisiweyo, okona kusetyenziswa kakhulu. Apha ngezantsi ndiza kugxila ekusetyenzisweni nasekusetyenzisweni kwe-seluplose eves kwizinto zokwakha ezinobuhlobo.
1. Kwipeyinti ye-Latex
Kwimveliso yepeyinti ye-Fetex, i-HydroxyEtheetheetheethy kufuneka ikhethwe. Ukucaciswa ngokubanzi kwe-viscofity yi-RT30000-500500CP, kunye ne-dosage yesalathiso ngokubanzi malunga ne-1.5 ‰ -2 ‰. Umsebenzi ophambili we-hydroxyythl kwipeyinti ye-Latex yeyokuthintela ukungqubana kweenkamba, i-Latement, kunye nokuzinza kwenqanaba lokwakhiwa: i-hydroxythyth selyulose ilula ukuyisebenzisa. Ingachithwa kumanzi abandayo kunye namanzi ashushu, kwaye ayichaphazeleki kwixabiso le-pH. Ingasetyenziswa phakathi kwexabiso le-2 ne-12. Kukho ezi ndlela zintathu zilandelayo:
I. Yongeza ngqo kwimveliso:
Le ndlela kufuneka inyule i-hydroxythl seluplose Amanyathelo asetyenziswayo ngolu hlobo lulandelayo: Kude kufike zonke izinto ze-granular ④ Yongeza ezinye izicelo zongezwa kunye ne-alkaline, njl njl.
Ⅱ. Ixhotywe ngotywala bukatywala:
Le ndlela inokukhetha uhlobo lwethutyana, kwaye inefuthe le-anti-mpulose. Inzuzo yale ndlela kukuba iguquguquka kakhulu kwaye inokutongelwa ngqo kwipeyinti ye-latex. Indlela yokulungiselela iyafana namanyathelo e-①-④.
Ⅲ. Ukulungiselela iipropathi ze-porridge
Kuba izinyibilikisi zendalo zizinto ezinqabileyo ze-Sholt Ezona zigqibo zisetyenziswayo zisetyenziswayo zisetyenziswayo zizinto eziphilayo zezinto eziphilayo zepeyinti, ezinje nge-gaylene glycol, i-propylene glycol kunye ne-probymers yefilimu (efana ne-dilyl ye-gelcol byl). I-Porridge ye-Holdroxythyl isellise inokulongezwa ngokuthe ngqo kwipeyinti. Qhubeka nokuvuselela kude kukhanyeswe ngokupheleleyo.
I-2, i-scraung doty
Okwangoku, ngokusingqongileyo obunobuhlobo obunganyangekiyo kwamanzi kwaye ukunyangeka kwe-scrun kwizixeko ezininzi kwilizwe lam kuye kwaxatyiswa ngabantu. Kule minyaka imbalwa idlulileyo, kuba i-DOTTY eyenziwe yi-glue yokwakha ikhupha i-formaldehyde igesi kunye ne-GEORORD YOKWENZA I-POLYIC ye-polymer ilungiselelwe yi-Acetal Wandson kwaye ilungiselelwe i-vinyl utywala kunye ne-follyadyehyde. Ke ngoko, le nto ishenxiswa ngabantu, kwaye ukuqalisa iimveliso ze-Elese eThersulose kutshintshwa yile nto, oko kukuthi, ukuphuculwa kwezinto zokwakha ezinobuhlobo kwindalo, selupelose kuphela kwento ekhoyo.
Kwi-iuto enganyangekiyo emanzini, yahlulwe yaye yancamathisela i-bubty yomgubo. Phakathi kwezi ntlobo zimbini ze-putty, i-methyl ye-methyl ye-methyl kunye ne-hydroxyl ye-methyl zikhethwe ngokubanzi. 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 ezingwevu, i-calcium ekhanyayo, i-calcium ye-geyscim, i-Gycium, i-GreyCum, i-Greycium, i-viscosity kunye nokungena . Isixa songezelelo simalunga ne-2 ‰ -3 ‰.
Ekwakhiweni kodonga lokukrokrela, kuba umhlaba osisiseko ulufula amanzi (inqanaba lokufumana amanzi le-Brick udonga lwe-Brick yi-3%), kunye Ukuvela kwehlabathi elingaphandle, ukuba i-DOTTY iphulukana namanzi ngokukhawuleza, iya kukhokelela kwimingxunya okanye ukususwa komda kunye nezinye izinto, ngaloo ndlela zibuthathaka amandla e-bume. Ngesi sizathu, ukongeza i-Ether Ither kuya kuyisombulula le ngxaki. Kodwa umgangatho we-filler, ngakumbi umgangatho we-calcium, ikwabaluleke kakhulu. Ngenxa yokuba i-seluplose ine-viscofity ephezulu, ikwandisa i-buoyty ye-putty, ivumela ukubamba ngexesha lokwakha, kwaye ukhululekile ngakumbi kwaye ugcinwe ekusebenzeni.
I-3. Ikhonkrithi yekhonkrithi
Ebudeni bekhonkrithi, ukufezekisa ngokwenene amandla okugqibela, isamente kufuneka ibe hhwane i-hydddy yokwakha ihlobo, udaka lwekhonkrithi luthathwa ngokukhawuleza, kwaye imilinganiselo ye-hydration ithathwayo ukuyigcina kwaye ifafazwe amanzi. Inkcitho yezixhobo kunye nokusebenza okungahambelaniyo, isitshixo kukuba amanzi aphezulu, kwaye i-hydication yangaphakathi ingaphelelanga, ke isisombululo sale ngxaki kukudibanisa i-Hydroplopy okanye iMethyl Secose kwikhonkrithi. Ukuchazwa kwe-Viscofity iphakathi kuka-20000-60000cps, isixa esongezelelekileyo simalunga ne-2 ‰ -3 ‰, kunye nexabiso lokugcina amanzi linganyuka lingaphezulu kwe-85%. Indlela yokuSetyenziswa kwikhonkrithi yekhonkrithi kukudibanisa umgubo owomileyo kwaye wongeza amanzi.
I-4. Kwindawo yokubeka phantsi, i-plasters plations kunye nodaka lwe-calking
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 zidrating gypsum, i-Bypsum yeGypsum, i-Gypsum, i-Gypsum, iTile.
I-Stucco Plaster luhlobo lwezinto ezikumgangatho ophezulu wokubekwa kweendonga zangaphakathi nophahla. Iindonga zenziwe zilungile kwaye zigudile, musani ukuyeka umgubo, musani ukuyeka umgubo, qinile, musani ukunyangwa, kwaye ninyange umlilo; I-plaster plaster luhlobo lodaka. Uhlobo olutsha lwebhodi yokukhanya kweBhodi yeBhodi yeBhodi ye-Stotive sisixhobo esinamathele senziwe nge-gypsim njengezinto ezisisiseko kwaye songeze izongezo ezahlukeneyo. Ilungele ukoyikwa phakathi kwezinto ezahlukeneyo zodonga. Ayisiyo inetyhefu, ingenaxabiso, ineempawu zamandla angaphambili, ukumiswa ngokukhawuleza kunye nokugxeka okuqinileyo, kwaye yinto exhasayo, kwaye yindawo yokuxhasa eyakha iibhodi kunye neebhloko;
Ezi mveliso ze-gypsim zinothotho lwemisebenzi eyahlukeneyo, ukongeza kwindima ye-gypsim kunye neefilimu ezinxulumene noko, umba ophambili kukuba i-Itelilose ye-Ether idlala indima ekhokelayo. Kuba i-gyppum yahlulahlulwe yaba yi-anhydrite kunye ne-hemimdrate gypsum, i-gypsum eyahlukileyo ineziphumo ezahlukeneyo ukusebenza, ukugcinwa kwamanzi, ukugcinwa kwamanzi kunye nokubuyiselwa kwamanzi kumisela umgangatho wezinto zokwakha zeGyppum. Ingxaki eqhelekileyo kwezi zixhobo ikhutshiwe, kwaye amandla okuqala akanakufikelelwa. Ukusombulula le ngxaki, yingxaki yokukhetha uhlobo lwesellulose kunye nendlela yokusetyenziswa kwe-restarter. Kule meko, i-methyl okanye i-hydroxypropyl methyl i-30000 inyuliwe. -60000cps, isixa esongeneyo siphakathi kwe-1.5 ‰ -2 ‰, kugxilwe kwi-seluplose kukugcinwa kwamanzi, ukubuyiswa kunye nokuthambisa.
Nangona kunjalo, akunakwenzeka ukuba ixhomekeke kwi-ether sether njenge-rearder, kwaye kuyimfuneko ukongeza i-cicric acid ukuxuba nokuyisebenzisa ukuze amandla okuqala angachaphazeli.
Iqondo lokugcina amanzi ngokubanzi libhekisa kwilahleko yendalo engabikho kwi-airsunce yangaphandle. Ukuba udonga lome kakhulu, ukufunxa kwamanzi kunye nokuphuma kwendalo kwisiseko sendalo kuya kubangela ukuba izinto ziphulukane namanzi ngokukhawuleza, kwaye ukungcungcutheka kunye nokuqhekeka kwaye kuyakwenzeka.
Le ndlela yokusetyenziswa ixutywe nomgubo owomileyo. Ukuba isisombululo silungisiwe, nceda ujonge kwindlela yokulungiselela yesisombululo.
I-5. Udaka lokuthintela
UHlolo loThekelo lweThermal luhlobo olutsha lwezinto ezingaphakathi kwi-Intermal i-Irmal Inven. Yinto eludongeni equlunqwe ngempahla yokufakelwa kobushushu, udaka kunye ne-binder. Kule nto, i-seluplose idlala indima ephambili ekwenzeni nasekukhuliseni amandla. Ngokukodwa khetha i-methyl seluplose nge-viscofity ephezulu (malunga ne-10000s), idosi ngokubanzi phakathi kwe-2 ‰ -3 ‰), kwaye indlela yokusetyenziswa yindlela yokudibanisa umgubo owomileyo.
I-6. Iarhente yokujonga
Iarhente ye-argenc20000p200cps, kunye ne-TIle Adhestive ingaphezulu kwe-60000cps. Kwi-arhente yojongano, isetyenziswa ikakhulu njenge-thi chukener, enokuphucula amandla amanye kunye nokunyangwa kukukhathalela.
