Ukuphucula ukusebenza kwezinto zokwakha - i-hydroxypropyl methylcellulose

I-Hydroxypropyl methylcellulose (i-HPMC ngokufutshane) yi-ether ebalulekileyo edibeneyo, eyi-polymer e-non-ionic yamanzi e-soluble, kwaye isetyenziswa kakhulu kukutya, amayeza, kwishishini lemichiza yemihla ngemihla, i-coating, i-polymerization reaction kunye nokwakhiwa njenge-dispersion suspension , ukuqina, emulsifying, ukuzinzisa kunye adhesives, njl, kwaye kukho umsantsa omkhulu kwimarike yasekhaya.

I-Hydroxypropyl methylcellulose isetyenziswa ngokubanzi kwishishini lokwakha njenge-agent-forming agent, i-binder, i-dispersant, i-stabilizer, i-thickener, umgqugquzeli wamanzi, njl.

Hydroxypropylmethylcellulose

Igama elipheleleyo lesiNgesi: Hydroxypropyl Methyl Cellulose IsiNgesi isishunqulelo: HPMC

Ngenxa yokuba i-HPMC ineempawu ezibalaseleyo ezifana nokutyeba, i-emulsification, ukwenza ifilimu, i-colloid ekhuselayo, ukugcinwa kokufuma, ukunamathela, ukuxhathisa i-enzyme kunye nokungasebenzi komzimba, isetyenziswa ngokubanzi kwiingubo, ukuphendula kwe-polymerization, izinto zokwakha, imveliso yeoli, iingubo, ukutya, amayeza, Iiseramikhi ezisetyenziswa mihla le, izixhobo zombane kunye nembewu yezolimo namanye amasebe.

izinto zokwakha

Kwizinto zokwakha, i-HPMC okanye i-MC idla ngokudibaniswa kwisamente, udaka, kunye nodaka ukuphucula izakhiwo kunye nokugcinwa kwamanzi.

Ingasetyenziswa njenge:

1). I-adhesive kunye ne-caulking agent ye-gypsum-based adhesive tape;

2). Ukudityaniswa kwezitena ezisekelwe kwisamente, iithayile kunye neziseko;

3). istucco esekwe kwiplasterboard;

4). Udaka olusekelwe kwisamente;

5). Kwifomula yepeyinti kunye nepeyinti yokususa.

I-Adhesive kwiithayile ze-ceramic

HPMC 15.3 iinxalenye

Perlite 19.1 iinxalenye

I-amide enamafutha kunye ne-cyclic thio ikhompawundi 2.0 iinxalenye

Isanti yesilika 50 iinxalenye

Iinxalenye ezingama-50 zamanzi

Isetyenziswa njengesongezo semathiriyeli yesamente ephezulu yokuqina:

Catelan isamente 100 iinxalenye

Asbestos 5 iinxalenye

Ukulungiswa kotywala bePolyvinyl 1 inxalenye

I-calcium silicate iinxalenye ezili-15

32 iinxalenye zamanzi

HPMC 0.8 iinxalenye

Ishishini lokupeyinta

Kushishino lwepeyinti, i-HPMC isetyenziswa kakhulu kwipeyinti ye-latex kunye nenxalenye yepeyinti ye-resin enyibilikayo yamanzi njenge-agent eyenza ifilimu, i-thickener, i-emulsifier kunye ne-stabilizer.

Ukumiswa kwePolymerization yePVC

Intsimi enezona mveliso zininzi zeHPMC kwilizwe lam kukunqunyanyiswa kwepolymerization yevinyl chloride. Kwi-polymerization yokumiswa kwe-vinyl chloride, inkqubo yokusabalalisa ichaphazela ngokuthe ngqo umgangatho we-resin ye-PVC yemveliso kunye nokusebenza kwayo kunye neemveliso; inokuphucula ukuzinza kwe-thermal ye-resin kunye nokulawula ukusabalalisa ubungakanani be-particle (oko kukuthi, ukulungelelanisa ubuninzi bePVC). Isixa se-HPMC senza i-0.025% ~ 0.03 yesiphumo sePVC%.

I-resin ye-PVC elungiselelwe ngumgangatho ophezulu we-HPMC, ukongeza ekuqinisekiseni ukuba intsebenzo ihlangabezana nomgangatho wesizwe, nayo ineempawu ezintle zomzimba, iimpawu ezibalaseleyo zamasuntswana kunye nokuziphatha okugqwesileyo kwe-rheological.

elinye ishishini

Amanye amashishini ikakhulu abandakanya izinto zokuthambisa, imveliso ye-oyile, izicoci, iiseramikhi zasekhaya kunye namanye amashishini.

amanzi anyibilikayo

I-HPMC yenye yeepolymers ezinyibilikayo emanzini, kwaye ukunyibilika kwayo kwamanzi kuhambelana nomxholo weqela le-methoxyl. Xa umxholo weqela le-methoxyl uphantsi, unokunyibilika kwi-alkali enamandla kwaye ayinayo indawo ye-gelation ye-thermodynamic. Ngokunyuka komxholo we-methoxyl, ivakalelwa ngakumbi ekudumbeni kwamanzi kwaye i-soluble kwi-alkali edibeneyo kunye ne-alkali ebuthathaka. Xa umxholo we-methoxyl ungaphezulu kwe-38C, unokunyibilika emanzini, kwaye unokunyibilika kwi-halogenated hydrocarbons. Ukuba iasidi periodic yongezwa HPMC, HPMC uya kukhawuleza ukusasaza emanzini ngaphandle kokuvelisa izinto zecaking ezinganyibilikiyo. Oku kubangelwa ikakhulu kukuba i-asidi ye-periodic inamaqela e-dihydroxyl kwindawo ye-ortho kwi-glycogen esasaziweyo.
