1. Dab tsi yog qhov tsim nyog viscosity ntawm HPMC?
- Aswerwer: Feem ntau, 100,000 Yuan yog txaus rau cov hmoov putty. Cov cai ua tshuaj khib nyiab ntau dua, thiab 150,000 Yuan yuav tsum tau siv yooj yim. Ntxiv mus, cov haujlwm tseem ceeb tshaj plaws ntawm HPMC yog dej tuav, ua raws li thickening. Nyob rau hauv cov hmoov putty, tsuav li lub taub dej ceev yog qhov zoo thiab lub viscosity yog tsawg (70,000-80,000), nws tseem ua tau. Ntawm chav kawm, qib siab dua viscosity, zoo dua cov txheeb ze cov dej rov qab khaws cia. Thaum lub viscosity tshaj 100,000, lub viscosity yuav cuam tshuam rau cov dej tuav tseg. Tsis ntau ntxiv lawm.
2. Dab tsi yog lub ntsiab lus tseem ceeb ntawm HPMC?
Lub ntsiab lus: Hydroxypropropyl cov ntsiab lus thiab viscosity, feem ntau cov neeg siv tau txhawj xeeb txog ob yam ntsuas no. Cov uas muaj cov ntsiab lus hydroxyproprots feem ntau muaj cov dej ua kom zoo dua. Ib qho nrog cov viscosity siab muaj cov dej siab zoo dua, tsis yog), thiab ib qho uas muaj viscosity siab yog siv tau zoo dua hauv cov xis.
3. Dab tsi yog qhov ua haujlwm tseem ceeb ntawm daim ntawv teev HPMC hauv cov hmoov uas muaj zaub mov, thiab nws puas tshwm sim chemically?
- Pertical hmoov, HPMC ua si peb lub luag haujlwm ntawm thickening, dej tuav thiab tsim kho. Thickening: cellulose tuaj yeem ua tuab rau ncua thiab ua kom cov tshuaj daws teeb meem nce thiab nqis, thiab tiv taus sagging. Dej khaws cia: Ua cov hmoov ua kom qhuav maj mam, thiab pab cov ntug dej tshauv kom muaj kev cuam tshuam hauv kev ua dej. Kev tsim kho: Cellulose muaj cov nyhuv muaj lubricating nyhuv, uas tuaj yeem ua rau cov hmoov puty muaj kev tsim kho zoo. HPMC tsis koom nrog kev siv tshuaj lom neeg, tab sis tsuas yog ua lub luag haujlwm pab pawg. Ntxiv cov dej rau cov hmoov putty thiab muab tso rau ntawm phab ntsa yog tshuaj lom neeg cov tshuaj tiv thaiv, vim tias cov tshuaj tshiab tau tsim. Yog tias koj tshem tawm cov hmoov putty ntawm phab ntsa los ntawm phab ntsa, thiab siv nws dua, nws yuav tsis ua haujlwm vim tias cov khoom siv hluav taws xob (calcium carbonate) tau tsim. ) ib yam nkaus. Lub ntsiab ntawm cov hmoov tshauv calcium hmoov yog: sib xyaw ntawm Ca (OHO (OH) 2-↓) nws tus kheej.
4. HPMC yog cov tsis-ionic cellulose ether, yog li dab tsi tsis-ionic?
Lub ntsiab lus: Nyob rau hauv Layman cov lus, tsis muaj i ions tshuaj uas yuav tsis ionize hauv dej. Ionization hais txog cov txheej txheem uas ib qho electrolyte rau hauv kev them nyiaj rau hauv kev them nyiaj rau hauv cov kuab tshuaj tshwj xeeb (xws li dej, cawv). Piv txwv li, sodium chloride (nacl), ntsev peb noj txhua hnub, yaj nyob rau hauv dej thiab chloride ions (cl) uas yog tsis zoo. Uas yog hais, thaum HPMC tau muab tso rau hauv dej, nws yuav tsis cais tawm rau hauv cov pej xeem, tab sis muaj nyob rau hauv daim ntawv ntawm molecules.
5. Puas muaj kev sib raug zoo ntawm qhov poob ntawm cov hmoov putty thiab HPMC?
--Swer: Cov hmoov poob ntawm cov hmoov putty yog feem ntau cuam tshuam nrog qhov zoo ntawm cov ntug dej tshauv, thiab muaj me ntsis los ua nrog HPMC. Cov ntsiab lus tsawg dua ntawm grey calcium thiab tus tsis raug cai ntawm sabo thiab ca (Oh) 2 hauv grey calcium yuav ua rau hmoov hmoov. Yog tias nws muaj qee yam ua nrog HPMC, ces yog tias cov dej tuav HPMC tsis zoo, nws tseem yuav ua rau hmoov hmoov
6. Yuav ua li cas xaiv HPMC haum rau cov laj thawj sib txawv?
Lub npe: kev thov ntawm cov hmoov putty: qhov yuav tsum tau muaj tsawg, thiab viscosity yog 100,000, uas yog txaus. Qhov tseem ceeb tshaj plaws yog kom dej kom zoo. Daim ntawv thov ntawm cug: qhov yuav tsum tau muaj, siab viscosity, 150,000 yog qhov zoo dua. Daim ntawv thov ntawm cov kua nplaum: Cov khoom tseem ceeb uas yuav tsum muaj viscosity siab.
