I-Hydroxypropyl Methyl Cellulose 9004-65-3 Enokusebenza Okuphezulu Kokugcina Amanzi

noma i-HPMCI-Hydroxypropyl methylcellulose(Igama le-INN: Hypromellose), ephinde yenziwe lula njenge-hydroxypropyl methylcellulose (HPMC), uhlobo lwe-non-ionic cellulose mixed ether. Iyi-polymer ehlanganisiwe, engasebenzi, ne-viscoelastic. I-Hydroxypropyl methylcellulose isetshenziswa kabanzi ekwakheni, ekudleni, kwezokwelapha nakwezinye izimboni.

Inombolo ye-HPMC CAS: 9004-65-3

Isakhiwo se-HPMC:

IKHODI YE-HS YE-HPMC: 3912390000

Impahla yamakhemikhali:

Ukubukeka: Impuphu emhlophe noma efana nayo.

Usayizi wezinhlayiya; Izinga lokudlula kwe-mesh engu-100 lingaphezu kuka-98.5%; Izinga lokudlula kwe-mesh engu-80 liyi-100%. Usayizi wezinhlayiya zezincazelo ezikhethekile wawusukela ku-mesh engu-40 kuya ku-60.

Ubuningi bokubona: 0.25-0.70g/cm (ngokuvamile cishe 0.5g/cm), amandla adonsela phansi athile 1.26-1.31.

Ukuncibilika: Kuncibilika emanzini nakwezinye izincibilikisi, njengesilinganiso esifanele se-ethanol/amanzi, i-propanol/amanzi, njll. Isixazululo samanzi sinomsebenzi wobuso. Ngokucaca okuphezulu nokusebenza okuzinzile, izinga lokushisa lejeli lezinhlobo ezahlukene lihlukile, ukuncibilika kuyashintsha nge-viscosity, i-viscosity iphansi futhi ukuncibilika kukhulu. Ukusebenza kwe-HPMC ngezincazelo ezahlukene kunomehluko othile. Ukuncibilika kwe-HPMC emanzini akuthinteki yinani le-PH.

I-HPMC ekhiqizwe nguLongou:

I-Longou ikhiqiza futhi ihlinzeka ngezinhlobo ezahlukene ze-HPMC kanye ne-HEMC (MODCELL®) zezinhlelo zokusebenza ezahlukene. Ngokuvamile, i-Longou HPMC iqukethe uchungechunge olubili lwe-HPMC, uchungechunge olulodwa lwe-HEMC kanye nemikhiqizo eguquliwe.

Izinhlobo ezijwayelekile:

I-Hydroxypropyl methylcellulose (HPMC) yi-cellulose ethers ebe namaqembu e-hydroxyl ku-cellulose chain athathelwe indawo yiqembu le-methoxy noma le-hydroxypropyl.It Kwenziwa ngokushintshashintsha okukhethekile kwe-cellulose kakotini emsulwa kakhulu ngaphansi kwezimo ze-alkaline. Eminyakeni yamuva nje, i-HPMC, njengengxube esebenzayo, idlala indima enkulusekugcinweni nasekuqineni kwamanzi embonini yokwakha futhi isetshenziswa kabanzi eizigqulo zokuxuba i-drymix, njenge-tile adhesive, ama-grout, i-plastering, i-wall putty, i-self leveling, i-insulation mortar njll.

Ngokuvamile, ngempuphu ye-putty, i-viscosity yeI-HPMCkwanele cishe ku-70,000 kuya ku-80,000. Ukugxila okuyinhloko ekusebenzeni kwayo kokugcina amanzi, kuyilapho umphumela wokujiya uncane kakhulu. Ku-mortar, izidingo ze-I-HPMCziphakeme, futhi i-viscosity idinga ukuba cishe yi-150,000, okungaqinisekisa ukuthi isebenza kangcono ku-cement mortar. Yiqiniso, ku-putty powder, inqobo nje uma ukusebenza kokugcinwa kwamanzi kwe-HPMC kukuhle, noma ngabe i-viscosity iphansi (70,000 kuya ku-80,000), kuyamukeleka. Kodwa-ke, ku-cement mortar, kungcono kakhulu ukukhetha i-HPMC ene-viscosity enkulu (engaphezu kwe-100,000), ngoba umphumela wayo wokugcinwa kwamanzi ubaluleke kakhulu kulesi simo.

Inkinga yokususwa kwempuphu ye-putty incike kakhulu kwikhwalithi ye-calcium hydroxide futhi ayihlobene kakhulu ne-HPMC. Uma okuqukethwe kwe-calcium ye-calcium hydroxide kuphansi noma isilinganiso se-CaO kanye ne-Ca(OH)2 singafaneleki, kungabangela ukuthi impuphu ye-putty iwe. Ngokuphathelene nomthelela we-HPMC, kubonakala kakhulu ekusebenzeni kwayo kokugcina amanzi. Uma ukusebenza kokugcina amanzi kwe-HPMC kukubi, kungase kube nomthelela othile ekususeni impuphu ye-putty.

Izidingo zokusebenzisa i-putty powder ziphansi kakhulu. I-viscosity engu-100,000 yanele. Isihluthulelo ukuba nezakhiwo ezinhle zokugcina amanzi. Ngokuphathelene nodaka, izidingo ziphakeme kakhulu kanti i-viscosity ephezulu iyadingeka, kanti umkhiqizo ongu-150,000 unomthelela ongcono.

(1) Imboni yokwakha: Njenge-ejenti yokugcina amanzi kanye ne-retarder ye-cement mortar, yenza i-mortar ikwazi ukupompa. Sebenzisa i-plaster, i-gypsum, i-putty powder noma ezinye izinto zokwakha njengezinamathelisi ukuze uthuthukise ukusebenza futhi wandise isikhathi sokusebenza. Ingasetshenziswa ukunamathisela ithayela le-ceramic, imabula, umhlobiso wepulasitiki, i-ejenti yokuqinisa i-paste, kanye nokunciphisa inani le-cement. Impahla yokugcina amanzi ye-HPMC ivimbela i-slurry ukuthi ingaqhekeki ngenxa yokoma ngokushesha kakhulu ngemva kokugcotshwa futhi ithuthukise amandla.

(2) Imboni yokukhiqiza i-ceramic: isetshenziswa kabanzi njengezinamathelisi ekwenziweni kwemikhiqizo ye-ceramic.h ngemva kokuqina.

(3) Imboni yezingubo zokumboza: Njengesithako sokujiya, isihlakazi kanye nesiqinisi embonini yezingubo zokumboza, inokuncibilika okuhle emanzini noma ezincibilikisini eziphilayo.

(4) Ukuphrinta uyinki: Njengesithambisi, isihlakazi kanye nesiqinisi embonini uyinki, inokuncibilika okuhle emanzini noma ezincibilikisini eziphilayo.

(5) Ipulasitiki: njenge-ejenti yokukhulula, isithambisi, i-lubricant, njll.

(6) I-Polyvinyl chloride: Njengoba iyi-dispersant ekukhiqizweni kwe-polyvinyl chloride, iyisiza esiyinhloko ekulungiseleleni i-PVC nge-suspension polymerization.

(7) Okunye: Lo mkhiqizo usetshenziswa kabanzi nasezikhumbeni, emikhiqizweni yephepha, ekulondolozweni kwezithelo nemifino, kanye nasembonini yezindwangu.
