1. Yintoni eyona njongo ye-hydroxypropyl methyl cellulose (HPMC)?
I-HPMC isetyenziswa ngokubanzi kwizinto zokwakha, iingubo, ii-resin zokwenziwa, iiseramikhi, amayeza, ukutya, amalaphu, ezolimo, izithambiso, icuba kunye namanye amashishini.
I-HPMC inokohlulwa ibe yibakala lokwakha, ibakala lokutya kunye nebakala lezonyango ngokwenjongo yalo.
Okwangoku, uninzi lweemveliso zasekhaya zikumgangatho wokwakha. Kwibakala lokwakha, i-putty powder isetyenziswe kwisixa esikhulu, malunga ne-90% isetyenziselwa i-putty powder, kwaye intsalela isetyenziselwa udaka lwesamente kunye neglue.
2. Kukho iindidi ezininzi ze-hydroxypropyl methyl cellulose (HPMC). Uthini umahluko phakathi kokusetyenziswa kwazo?
HPMC inokohlulwa ibe uhlobo olukhawulezileyo kunye nohlobo ukunyibilika ashushu.
Imveliso ekhawulezileyo isasazeka ngokukhawuleza emanzini abandayo kwaye iyanyamalala emanzini. Ngeli xesha, ulwelo akukho viscosity, kuba HPMC isasazwe kuphela emanzini kwaye ayinyibiliki ngokwenene. Malunga nemizuzu emi-2, i-viscosity ye-liquid yanda ngokuthe ngcembe, yenza i-colloid ebonakalayo ebonakalayo.
Uhlobo olukhawulezayo, uluhlu olubanzi lwezicelo, lunokusetyenziswa kwi-putty powder kunye nodaka, kunye neglue elulwelo kunye nepeyinti.
Imveliso eshushu-encibilikayo, xa idibana namanzi abandayo, inokusasazeka ngokukhawuleza emanzini ashushu kwaye ilahleke emanzini ashushu. Xa amaqondo obushushu ehla ukuya kwiqondo elithile lobushushu, i-viscosity ibonakala kancinane de i-viscous colloid ecacileyo yenziwe.
Uhlobo olushushu olunyibilikayo lunokusetyenziswa kuphela kwi-putty powder kunye nodaka.
3. Ziziphi iindlela zokuchithwa kwe-hydroxypropyl methyl cellulose (HPMC)?
Indlela yokuchithwa kwamanzi ashushu: Kuba i-HPMC ayinyibiliki emanzini ashushu, i-HPMC inokusasazwa ngokufanayo kumanzi ashushu kwinqanaba lokuqala, kwaye emva koko inyibilike ngokukhawuleza xa ipholile. Iindlela ezimbini eziqhelekileyo zichazwa ngolu hlobo lulandelayo:
(1) Beka umlinganiselo ofunekayo wamanzi ashushu kwisikhongozelo uze ufudumale ukuya kutsho kuma-70°C. Ngokuthe ngcembe yongeza i-hydroxypropyl methylcellulose ngokushukumisa kancinane, qalisa i-HPMC edadayo phezu kwamanzi, kwaye ngokuthe ngcembe wenze i-slurry, kwaye upholise uludaka ngokushukumisa.
(2). Yongeza i-1/3 okanye i-2/3 yomlinganiselo ofunekayo wamanzi kwisikhongozeli kwaye uyifudumeze ukuya kuma-70°C. Ngokwendlela engentla, ukusasaza i-HPMC ukulungiselela i-slurry yamanzi ashushu; uze ungeze inani eliseleyo lamanzi abandayo kwi-slurry yamanzi ashushu. Kwi-slurry, pholisa umxube emva kokuvuselela.
Indlela yokuxuba umgubo: Xuba i-HPMC yomgubo kunye nesixa esikhulu sezinye izithako zomgubo kunye nomxube, uze wongeze amanzi ukuze unyibilike, emva koko i-HPMC inokunyibilika ngeli xesha ngaphandle kokuhlangana, kuba ikona nganye encinci, kukho intwana ye-HPMC. Umgubo uya kunyibilika ngokukhawuleza xa udibana namanzi.
4. Indlela yokugweba umgangatho we-hydroxypropyl methylcellulose (HPMC) ngokulula kunye ne-intuitively?
(1) Ubumhlophe: Nangona ubumhlophe bungenakucacisa ukuba i-HPMC kulula ukuyisebenzisa, kwaye ukuba i-brightener yongezwa kwinkqubo yokuvelisa, iya kuchaphazela umgangatho wayo. Nangona kunjalo, uninzi lweemveliso ezilungileyo zinobumhlophe obuhle.
(2) Ukulunga: Ukulunga kwe-HPMC ngokuqhelekileyo yi-80 mesh kunye ne-100 mesh, i-120 mesh ingaphantsi, i-fineness ye-fineness, ingcono ngokubanzi.
(3) Ukuhanjiswa: Emva kokubeka i-HPMC emanzini ukwenza i-colloid ebonakalayo, jonga ukuhanjiswa kwayo. Okukhona ukuhanjiswa, kungcono, kubonisa ukuba kukho izinto ezinganyibilikiyo ngaphakathi.
(4) Umlinganiselo: okukhona umlinganiselo omkhulu, unzima ngakumbi. Ukucaciswa okuphezulu ngokuqhelekileyo kubangelwa umxholo ophezulu we-hydroxypropyl kuwo, kwaye uphakamileyo umxholo we-hydroxypropyl, ngcono ukugcinwa kwamanzi.
5. Zeziphi iimpawu eziphambili zobugcisa ze-hydroxypropyl methyl cellulose (HPMC)?
Umxholo we-Hydroxypropyl kunye ne-viscosity, uninzi lwazo lunenkxalabo malunga nezi zikhombisi zimbini. Ukugcinwa kwamanzi ngokuqhelekileyo kungcono kwabo banomxholo ophezulu we-hydroxypropyl. I-viscosity ephezulu, ukugcinwa kwamanzi, isalamane (kunokuba i-absolute) ingcono, kunye ne-viscosity ephezulu, isetyenziswe ngcono kwi-samente mortar.
6. Zeziphi ezona zixhobo ziphambili ze-hydroxypropyl methyl cellulose (HPMC)?
Izinto eziphambili ze-HPMC: i-cotton ecocekileyo, i-methyl chloride, i-propylene oxide, njl.
7. Yintoni umsebenzi oyintloko wokusetyenziswa kwe-hydroxypropyl methyl cellulose (HPMC) kwi-putty powder? Ngaba kukho ukusabela kweekhemikhali?

Ukujiya: Iselulosi inokujiya ukuze inqunyanyiswe kwaye igcine iyunifomu yesisombululo kunye nokunyuka nokuhla, kunye nokuchasana nokudodobala.
Ukugcinwa kwamanzi: yenza i-putty powder yome kancinci, kwaye uncedise i-calcium engwevu ukuba isabele phantsi kwesenzo samanzi.
Ukwakhiwa: I-Cellulose inefuthe lokuthambisa, elinokwenza ukuba i-putty powder ibe nokusebenza kakuhle.
I-HPMC ayithathi nxaxheba kuyo nayiphi na i-chemical reaction, idlala indima exhasayo kuphela.
8. Yintoni ivumba le-hydroxypropyl methyl cellulose (HPMC)?
I-HPMC eveliswa yindlela yokunyibilikisa isebenzisa i-toluene kunye ne-isopropanol njenge-solvent. Ukuba ayihlanjwanga kakuhle, izakuba nevumba elishiyekileyo.
9. Indlela yokukhetha i-hydroxypropyl methylcellulose (HPMC) efanelekileyo ngeenjongo ezahlukeneyo?
Ukusetyenziswa kwe-putty powder: imfuno iphantsi, i-viscosity yi-100,000, yanele, into ebalulekileyo kukugcina amanzi angcono.
Ukusetyenziswa komdaka: iimfuno eziphezulu, i-viscosity ephezulu, i-150,000 ingcono.
Ukusetyenziswa kweglue: iimveliso ezikhawulezayo ziyafuneka, kunye ne-viscosity ephezulu.
10. Ukusetyenziswa kwe-hydroxypropyl methyl cellulose (HPMC) kwi-putty powder, yintoni ebangela ukuba i-putty powder ivelise iibhubhu?
