FAQS
HPMC nomaI-Hydroxypropyl methylcellulose(Igama le-INN: I-Hypromellose), ephinde yenziwe lula njenge-hydroxypropyl methylcellulose (HPMC), iwuhlobo lwe-ether engeyona i-ionic cellulose exutshwe. I-semi-synthetic, engasebenzi, i-viscoelastic polymer. IHydroxypropyl methylcellulose isetshenziswa kabanzi ekwakheni, ekudleni, kwezokwelapha, nakwezinye izimboni.
I-HPMC CAS No.: 9004-65-3
Isakhiwo se-HPMC:
IKHODI YE-HPMC HS: 3912390000
Isakhiwo samakhemikhali:
Ukubukeka: Impushana emhlophe noma efana nayo.
Usayizi wezinhlayiya; Izinga lokuphasa nge-100 mesh lingaphezulu kwama-98.5%; Izinga lokuphasa nge-80 mesh ngu-100%. Usayizi wezinhlayiya zokucaciswa okukhethekile wawusukela kuma-mesh angama-40 kuye kwangama-60.
Ukuminyana okubonakalayo: 0.25-0.70g/cm (imvamisa cishe ngo-0.5g/cm), amandla adonsela phansi athile 1.26-1.31.
Ukunyibilika: Kuncibilika emanzini nakwezinye izincibilikisi, njengengxenye efanele ye-ethanol/amanzi, i-propanol/amanzi, njll. Isixazululo esinamanzi sinomsebenzi ongaphezulu. Ngokubonakala okuphezulu nokusebenza okuzinzile, izinga lokushisa lejeli lokucaciswa okuhlukile lihlukile, ukuncibilika kushintsha nge-viscosity, i-viscosity iphansi futhi ukuncibilika kukhulu. Ukusebenza kwe-HPMC ngezicaciso ezihlukene kunomehluko othile. Ukuhlakazwa kwe-HPMC emanzini akuthintwa ivelu ye-PH.
I-HPMC ekhiqizwe ngu-Longou:
I-Longou ikhiqiza futhi ihlinzeka ngezinhlobo ezahlukene ze-HPMC kanye ne-HEMC(MODCELL®) kuzinhlelo zokusebenza ezahlukene. Ngokuvamile, i-Longou HPMC iqukethe uchungechunge olubili lwe-HPMC, uchungechunge olulodwa lwe-HEMC nemikhiqizo eguquliwe.
Izinhlobo ezijwayelekile:
HPMC LK

I-Hydroxypropyl methylcellulose (HPMC) ama-cellulose ether abe namaqembu e-hydroxyl ochungechungeni lwe-cellulose esikhundleni seqembu le-methoxy noma le-hydroxypropyl.It yenziwa nge-etherification ekhethekile ye-cotton cellulose ehlanzekile kakhulu ngaphansi kwezimo ze-alkali. Eminyakeni yakamuva, i-HPMC, njengenhlanganisela esebenzayo, idlala indima enkulusekugcinweni kwamanzi kanye nokuqina embonini yezokwakha futhi isetshenziswa kabanzi kui-drymix mortars, njenge-adhesive tile, grouts, plastering, wall putty, self leveling, insulation mortar nokunye.
Ngokuvamile, i-putty powder, i-viscosity yeI-HPMCkwanele cishe ku-70,000 kuya ku-80,000. Okugxilwe kakhulu ekusebenzeni kwayo kokugcinwa kwamanzi, kuyilapho umphumela wokujiya umncane uma kuqhathaniswa. Ngodaka, izimfuneko zeI-HPMCziphakeme, futhi i-viscosity idinga ukuba ibe ngu-150,000, engaqinisekisa ukuthi isebenza kangcono odakeni lukasimende. Yiqiniso, ku-putty powder, inqobo nje uma ukusebenza kokugcinwa kwamanzi kwe-HPMC kuhle, noma ngabe i-viscosity iphansi (70,000 kuya ku-80,000), iyamukeleka. Kodwa-ke, odakeni lukasimende, kungcono kakhulu ukukhetha i-HPMC ene-viscosity enkulu (ngaphezu kuka-100,000), ngoba umphumela wayo wokugcina amanzi ubaluleke kakhulu kulesi simo.
Inkinga yokukhishwa kwe-putty powder ngokuyinhloko incike kwikhwalithi ye-calcium hydroxide futhi ayihlangene kancane ne-HPMC. Uma okuqukethwe kwe-calcium ye-calcium hydroxide iphansi noma isilinganiso se-CaO ne-Ca(OH)2 singalungile, kungase kubangele ukuba i-putty powder iwe. Mayelana nomthelela we-HPMC, ibonakala kakhulu ekusebenzeni kwayo kokugcinwa kwamanzi. Uma ukusebenza kokugcinwa kwamanzi kwe-HPMC kungalungile, kungase futhi kube nomthelela othile ekukhishweni kwe-putty powder.
Izidingo zokusetshenziswa kwe-putty powder ziphansi kakhulu. I-viscosity ye-100,000 yanele. Okubalulekile ukuthi ube nezindawo ezinhle zokugcina amanzi. Ngokuphathelene nodaka, izidingo ziphakeme kakhulu futhi i-viscosity ephakeme iyadingeka, futhi umkhiqizo we-150,000 unomphumela ongcono.
(1) Imboni yezokwakha: Njenge-ejenti egcina amanzi futhi ibuyisela emuva udaka lukasimende, yenza udaka lumpompeke. Sebenzisa i-plaster, i-gypsum, i-putty powder noma ezinye izinto zokwakha njengezinamathiselo ukuze uthuthukise ukusebenza futhi welule isikhathi sokusebenza. Ingasetshenziselwa ukunamathisela ithayela le-ceramic, imabula, umhlobiso wepulasitiki, unamathisele i-ejenti yokuqinisa, nokunciphisa inani likasimende. Impahla egcina amanzi ye-HPMC ivimbela udaka ekuqhekekeni ngenxa yokoma ngokushesha ngemva kokugcotshwa futhi kukhulisa amandla.
(2) Imboni yokukhiqiza i-Ceramic: isetshenziswa kabanzi njengezinamatheliso lapho kwakhiwa imikhiqizo yobumba.h ngemva kokuqina.
(3) Imboni yokumboza: Njenge-thickener, dispersant kanye ne-stabilizer embonini yokumboza, inokuncibilika okuhle emanzini noma ku-organic solvents.
(4) Ukuphrinta kukayinki: Njengokuqina, ukuhlakazeka kanye nokuqiniswa embonini kayinki, inokuncibilika okuhle emanzini noma kumakhemikhali aphilayo.
(5) Amapulastiki: njenge-ejenti eyenza ukukhululwa, okokuthambisa, okokugcoba, njll.
(6) I-Polyvinyl chloride: Njenge-dispersant ekukhiqizeni i-polyvinyl chloride, iwumsizi oyinhloko ekulungiseleleni i-PVC ngokumiswa kwe-polymerization.
(7) Abanye: Lo mkhiqizo futhi usetshenziswa kabanzi esikhumbeni, emikhiqizweni yephepha, ekulondolozweni kwezithelo nemifino, nasembonini yendwangu.
