Ukuphucula ukusebenza kwezixhobo zokwakha – i-hydroxypropyl methylcellulose

I-Hydroxypropyl methylcellulose (i-HPMC ngamafutshane) yi-ether exutyiweyo ebalulekileyo, eyi-polymer engeyiyo i-ionic enyibilikayo emanzini, kwaye isetyenziswa kakhulu ekutyeni, kumayeza, kushishino lweekhemikhali zemihla ngemihla, ekugqumeni, ekuphenduleni kwe-polymerization nasekwakheni njenge-dispersion suspension, thickening, emulsifying, stabilizing kunye ne-adhesives, njl.njl., kwaye kukho umsantsa omkhulu kwimarike yasekhaya.

I-Hydroxypropyl methylcellulose isetyenziswa kakhulu kwishishini lokwakha njenge-arhente yokwenza ifilimu, i-binder, i-dispersant, i-stabilizer, i-thickener, i-water promoter, njl.njl., kwaye ibe yimveliso ebalaseleyo ekhange ingqalelo ukusukela oko yasungulwa kumgca.

I-Hydroxypropylmethylcellulose

Igama elipheleleyo lesiNgesi: Hydroxypropyl Methyl Cellulose Isifinyezo sesiNgesi: HPMC

Ngenxa yokuba i-HPMC ineempawu ezintle kakhulu ezifana nokutyeba, i-emulsification, i-film forming, i-protective colloid, i-moisture retention, i-adhesion, i-enzyme resistance kunye ne-metabolism inertness, isetyenziswa kakhulu kwiingubo, i-polymerization reactions, izixhobo zokwakha, imveliso yeoyile, amalaphu, ukutya, amayeza, ii-ceramics ezisetyenziswa imihla ngemihla, izixhobo ze-elektroniki kunye nembewu yezolimo kunye namanye amasebe.

izixhobo zokwakha

Kwizinto zokwakha, i-HPMC okanye i-MC idla ngokufakwa kwisamente, kwi-mortar, nakwi-mortar ukuphucula izakhiwo kunye neempawu zokugcina amanzi.

Ingasetyenziswa njenge:

1). I-arhente yokuncamathelisa kunye ne-caulking yeteyiphu yokuncamathelisa esekwe kwi-gypsum;

2). Ukubopha izitena, iithayile kunye neziseko ezisekelwe kwisamente;

3). I-stucco esekwe kwi-plasterboard;

4). Iplasta yolwakhiwo esekwe kwisamente;

5). Kwifomyula yokususa ipeyinti kunye nepeyinti.

Ishishini lepeyinti

Kwishishini lokupenda, i-HPMC isetyenziswa kakhulu kwipeyinti yelatex kunye nezixhobo zepeyinti yeresin enyibilikayo emanzini njenge-arhente yokwenza ifilimu, i-thickener, i-emulsifier kunye ne-stabilizer.

Ukumiswa kwePolymerization yePVC

Intsimi esetyenziswa kakhulu kwiimveliso ze-HPMC kwilizwe lam yi-suspension polymerization ye-vinyl chloride. Kwi-suspension polymerization ye-vinyl chloride, inkqubo yokusasazwa ichaphazela ngokuthe ngqo umgangatho we-resin yemveliso ye-PVC kunye nokucutshungulwa kwayo kunye neemveliso; inokuphucula uzinzo lobushushu be-resin kwaye ilawule ukusasazwa kobungakanani be-particle (oko kukuthi, ukulungisa uxinano lwe-PVC). Ubungakanani be-HPMC buyi-0.025% ~ 0.03 yemveliso ye-PVC%.

I-resin ye-PVC elungiselelwe yi-HPMC esemgangathweni ophezulu, ukongeza ekuqinisekiseni ukuba ukusebenza kwayo kuyahambelana nomgangatho wesizwe, ikwanazo neempawu zomzimba ezilungileyo, iimpawu zeesuntswana ezibalaseleyo kunye nokuziphatha okuhle kakhulu kwe-rheological yokunyibilika.

amanye amashishini

Eminye imizi-mveliso ibandakanya ikakhulu izinto zokuthambisa, imveliso yeoyile, izicoci, izinto zodongwe zasekhaya kunye neminye imizi-mveliso.

amanzi anyibilikayo

I-HPMC yenye yeepolymers ezinyibilikayo emanzini, kwaye ukunyibilika kwayo emanzini kunxulumene nomxholo weqela le-methoxyl. Xa umxholo weqela le-methoxyl uphantsi, inokunyibilika kwi-alkali enamandla kwaye ayinayo indawo ye-thermodynamic gelation. Njengoko umxholo we-methoxyl usanda, ivakalelwa ngakumbi kukudumba kwamanzi kwaye iyanyibilika kwi-alkali enyibilikisiweyo kunye ne-alkali ebuthathaka. Xa umxholo we-methoxyl ungaphezulu kwe-38C, inokunyibilika emanzini, kwaye inokunyibilika nakwii-hydrocarbons ze-halogenated. Ukuba i-asidi ye-periodic yongezwa kwi-HPMC, i-HPMC iya kusasazeka ngokukhawuleza emanzini ngaphandle kokuvelisa izinto ezingenakunyibilika. Oku kungenxa yokuba i-asidi ye-periodic inamaqela e-dihydroxyl kwindawo ye-ortho kwi-glycogen esasazekileyo.
