Hydroxypropyl methylrcellellase hpmc budada ah

1. Guudmar

Hydroxypropylylul bylulose (HPMC) waa ehel aan lahayn oo cher-ka ah oo laga sameeyay sheyga polymer dabiiciga ah - cellulose iyada oo loo marayo hababka kiimikada ee taxanaha ah. Budada @droxypropylylulose (HPMC) waa ubaxyo aan dhadhan lahayn, oo aan sun lahayn, kaas oo lagu kala diri karo biyo qabow, kaas oo leh xayndaab, nashaadaad, nashaadaadyo dusha sare ah, haynta qoyaanka iyo xargaha coature.

Hydroxypropylkylylulose (HPMC) waxaa loo isticmaali karaa dhisidda qalabka, jaakadaha, isugeynta isku-darka, dhoobada, dawada, dharka, beeraha, beeraha, warshadaha tubaakada iyo warshadaha tubaakada.
2,Faahfaahinta alaabada iyo alaabada kala-soocidda waxay u qaybsan yihiin nooca biyaha qabow iyo nooca caadiga ah
Faahfaahinta guud ee tilmaamaha hydroxypropyl bylule

Faahfaahinta viscosity

3,dabeecadda wax soo saarka

Guryaha: Alaabtaani waa budo cad ama cadaan ah, ur la'aan, dhadhan la'aan iyoaan sun lahayn.

Xoolaha biyaha iyo awoodda qarosiinta: sheygan waxaa lagu kala diri karaa biyo qabow si loo sameeyo xalka viscous ee hufan.

Kala-diridda koollada dabiiciga ah: maxaa yeelay waxay ka kooban tahay xaddi badan oo ka mid ah rydrophopobic of of of of of of methoxyk ', Alaabtan waxaa lagu kala diri karaa qaar ka mid ah solvents-ka dabiiciga ah, waxaana sidoo kale lagu kala diri karaa dareeraha lagu qaso biyaha iyo arinta dabiiciga ah.

Iska caabbinta milixda: Maaddaama sheygan uu yahay polymer aan inoonic ', waa mid xasilloon oo ah xalka aqueous ee milixda birta ah ama elektrololytes-ka dabiiciga ah.

Waxqabadka dusha sare: xalka aqueous ee sheygan wuxuu leeyahay nashaadaadyo dusha sare ah, wuxuuna leeyahay shaqooyin iyo guryo sida emulsific, colloid-ka iyo xasilloonida qaraabada.

Qulqulka kuleylka: Marka xalka aqueous ee badeecadan lagu kululeeyo heerkul gaar ah, waxay noqotaa mid opaque ilaa ay ka samayso gobolka (poly), si xalka uu u lumiyo viscosity. Laakiin ka dib qaboojinta, waxay mar kale u rogi doontaa xalka asalka ah. Heerkulka uu guluubeyntu dhaco waxay kuxirantahay nooca sheyga, uruurinta xalka iyo heerka kuleylka.

PH Deganaansho: Muuqaalka xalka aqueous ee sheygan waa mid deggan oo ka dhex jira FR3.0-11.0.

Saamaynta biyo-haynta

Qaab-haynta HADDII: Marka la barbar dhigo polymers kale oo biyo-ku-milicsan, xalka aqueous ee sheygan wuxuu leeyahay guryo kedis ah oo proces ah. Intaas waxaa ku jira awooda lagu hayo qaabka badeecada dhoobada laga soo saaray ee aan is beddelin.

Saliidaha: Ku darista sheygan wuxuu yareyn karaa isbadalka khilaafaadka wuxuuna hagaajin karaa saliidaha alaabada dhoobada la soo saaray iyo alaabada sibidhka.

Guryaha sameynta filimka

4. Guryaha jireed iyo kiimikada

Cabbirka walxaha

Heerkulka kaarboon: 280 ~ 300 ℃

Cufnaanta muuqata: 0.25 ~ 0.70 / cm culays gaar ah 1.26 ~ 1.31

Heerkulka qulqulka: 190 ~ 200 ℃ ℃

Xiisadda dusha sare: 2% Xalka aqueous waa 42 ~ 56dyn / cm

Xoolaha: Ku dhex milma biyaha iyo waxyaabaha qaarkood, xalka aqueous wuxuu leeyahay nashaadaad dusha sare. Daahfurnaan sare. Waxqabadka xasilloon, isbedelada jilitaanka ee viscosity, hoos u dhaca cod-galka, kuwa kor u qaadida jilitaanka.

HIPMC sidoo kale waxay leedahay astaamaha awooda qaro weyn, iska caabbinta milixda, xasilloonida biyaha, haynta biyaha, xasilloonida cabirka, iyo noocyo ballaaran oo ah iska caabbinta, iyo kala-duwanaanta enzyme, kala firidhsan iyo wada-noolaansho.

Shan, ujeedada ugu weyn

Fasalka warshadaha ee HPMC waxaa inta badan loo isticmaalaa sidii wax ku fidin in la soo saaro soosaarka polyvinyl chloride chloride, waana wakiilka kaaliyaha ugu weyn ee diyaarinta PVC by polymommurize. In addition, it can be used as a thickener, stabilizer, emulsifier, excipient, and water-retaining agent in the production of other petrochemicals, coatings, building materials, paint removers, agricultural chemicals, inks, textile printing and dyeing, ceramics, paper, cosmetics, etc. , film forming agent, etc. The application in synthetic resins can make the obtained products have the characteristics of regular and Qurub dabacsan, oo ku habboon culays gaar ah iyo wax qabad ku habboon oo shaqeynaya, sidaa darteed asal ahaan waxay ku beddelaan gelatin iyo aalkolada polyvinyl ee kala duwanaanshaha.

Lix habab kala sooc ah:

(1). Qaado qaddarka biyaha ee loo baahan yahay, ku rid weel kuna kuleylka ka sarreeya 80 ° C, oo si tartiib tartiib ah ugu dar sheygan si tartiib tartiib ah. Cilmigu wuxuu ku saleeyaa dusha sare ee biyaha marka hore, laakiin si tartiib tartiib ah ayaa loo kala firdhiyaa si loo sameeyo mid jilicsan oo isku mid ah. Xalka ayaa la qaboojiyey iyadoo ay kareyso.

(2). Bedel ahaan, kuleyl 1/3 ama 2/3 biyaha kulul ilaa ka sareeya 85 ° C, ku dar cellulose si aad u hesho sturry biyo kulul, ka dibna ku dar kareyso biyaha qabow, oo qaboojiya isku dar ah ka dib.

(3). Mesh katirsan belulose waa wax fiican, oo waxay u jirtaa sidii shaqsiyaad yar yar oo ah walxaha si siman u kici kara, oo ay si dhakhso ah u milmayaan marka ay buuxiso biyaha loo baahan yahay.

(4). Si tartiib ah oo siman ugu dar unugyada unugyada heerkulka qolka, kareyso si isdaba joog ah ilaa xalka daah furnaanta la sameeyo.
