FAQS
HPMC okanyeIHydroxypropyl methylcellulose(Igama le-INN: I-Hypromellose), eyenziwe lula njenge-hydroxypropyl methylcellulose (HPMC), luhlobo lwe-non-ionic cellulose exutywe i-ether. Yi-semi-synthetic, engasebenzi, i-viscoelastic polymer. IHydroxypropyl methylcellulose isetyenziswa kakhulu kulwakhiwo, ukutya, amayeza, nakwamanye amashishini.
HPMC CAS No.: 9004-65-3
Ulwakhiwo lwe-HPMC:
IKHOWUDI ye-HPMC HS: 3912390000
Ipropati yeMichiza:
Ukubonakala: Umgubo omhlophe okanye omhlophe ofanayo.
Ubungakanani besuntswana; Ireyithi yokupasa i-100 mesh ingaphezulu kwe-98.5%; Ireyithi yokupasa ye-80 mesh yi-100%. Ubungakanani be-particle ye-Special specifications yayisuka kwi-40 ukuya kwi-60 mesh.
Ubuninzi obubonakalayo: 0.25-0.70g / cm (ngokuqhelekileyo malunga ne-0.5g / cm), ubunzima obuthile 1.26-1.31.
I-Solubility: I-Soluble emanzini kunye nezinye izinyibilikisi, ezifana nomlinganiselo ofanelekileyo we-ethanol / amanzi, ipropanol / amanzi, njl. Ngokubonakala okuphezulu kunye nokusebenza okuzinzile, ukushisa kwejeli yeenkcukacha ezahlukeneyo kuyahluka, utshintsho lwe-solubility kunye ne-viscosity, i-viscosity iphantsi kwaye i-solubility inkulu. Ukusebenza kwe-HPMC eneenkcukacha ezahlukeneyo kunomahluko othile. Ukuchithwa kwe-HPMC emanzini akuchatshazelwa lixabiso le-PH.

IHydroxypropyl methylcellulose (HPMC) zii-ether ze-cellulose ezibe namaqela e-hydroxyl kwikhonkco leselulosi endaweni ye-methoxy okanye iqela le-hydroxypropyl.It yenziwe nge-etherification ekhethekileyo ye-cotton cellulose ecocekileyo kakhulu phantsi kweemeko ze-alkaline. Kwiminyaka yakutshanje, i-HPMC, njenge-admixture esebenzayo, idlala indima enkulusekugcineni amanzi kunye nokutyeba kushishino lokwakha kwaye isetyenziswa ngokubanzi kwii-drymix mortars, njenge-adhesive tile, i-grouts, i-plastering, i-putty eludongeni, ukuzilinganisa, udaka lwe-insulation kunye njl.
Ngokuqhelekileyo, i-putty powder, i-viscosity yeHPMCyanele malunga nama-70,000 ukuya kuma-80,000. Ingqwalasela ephambili kukusebenza kwayo kokugcinwa kwamanzi, ngelixa isiphumo sokuqina sincinci. Ngodaka, iimfuno zeHPMCziphezulu, kwaye i-viscosity kufuneka ibe malunga ne-150,000, enokuqinisekisa ukuba isebenza ngcono kwi-samente yodaka. Ngokuqinisekileyo, kwi-putty powder, ngokude nje ukuba ukugcinwa kwamanzi kusebenze kwe-HPMC kulungile, nokuba i-viscosity iphantsi (i-70,000 ukuya kwi-80,000), iyamkeleka. Nangona kunjalo, kumdaka we-samente, kulungele ngakumbi ukukhetha i-HPMC ene-viscosity enkulu (ngaphezu kwe-100,000), kuba umphumo wayo wokugcina amanzi ubaluleke kakhulu kule meko.
Ingxaki yokukhutshwa kwe-putty powder ngokuyinhloko ixhomekeke kumgangatho we-calcium hydroxide kwaye ayinanto encinci ne-HPMC. Ukuba umxholo we-calcium we-calcium hydroxide uphantsi okanye umlinganiselo we-CaO kunye ne-Ca (OH) 2 awufanelekanga, unokubangela ukuba i-putty powder iwe. Ngokuphathelele impembelelo ye-HPMC, ibonakaliswe ikakhulu ekusebenzeni kwayo kokugcinwa kwamanzi. Ukuba ukusebenza kokugcinwa kwamanzi kwe-HPMC kubi, kunokuba nefuthe elithile kwi-depowdering of putty powder.
Iimfuno zokusetyenziswa kweputty powder ziphantsi. I-viscosity ye-100,000 yanele. Undoqo kukuba neempawu ezilungileyo zokugcina amanzi. Ngokumalunga nodaka, iimfuno ziphezulu kwaye i-viscosity ephezulu iyafuneka, kwaye imveliso ye-150,000 inesiphumo esingcono.
(1) Ishishini lokwakha: Njengearhente yokugcina amanzi kunye ne-retarder yodaka lwesamente, lenza ukuba udaka lumpompe. Sebenzisa i-plaster, i-gypsum, i-putty powder okanye ezinye izinto zokwakha njengezinto zokuncamathelisa ukuphucula ukusetyenziswa kunye nokwandisa ixesha lokusebenza. Ingasetyenziselwa ukuncamathelisa i-tile ye-ceramic, i-marble, i-plastic decoration, i-agent yokuqinisa i-agent, kunye nokunciphisa inani le-samente. Ipropathi yokugcina amanzi ye-HPMC ikhusela i-slurry ekuqhekekeni ngenxa yokoma ngokukhawuleza emva kokuthambisa kunye nokwandisa amandla.
(2) Ishishini lokwenziwa kwe-Ceramic: isetyenziswa ngokubanzi njengezinto zokuncamathelisa xa kusenziwa iimveliso zeceramic.h emva kokuqina.

(4) I-inki yoshicilelo: Njenge-thickener, dispersant kunye ne-stabilizer kwishishini le-inki, inonyibiliko oluhle emanzini okanye kwizinyibilikisi zendalo.
(5) Iiplastiki: njenge-ejenti yokukhululwa, i-softener, i-lubricant, njl.
(6) I-Polyvinyl chloride: Njengoko i-dispersant kwimveliso ye-polyvinyl chloride, iyona nto incedisayo ekulungiseleleni i-PVC ngokumiswa kwe-polymerization.
(7) Abanye: Le mveliso ikwasetyenziswa kakhulu kwisikhumba, iimveliso zephepha, ukugcinwa kweziqhamo nemifuno, kunye noshishino lwamalaphu.
