Budada Putty-hydroxypropyl methylcellulose

1. Maxay yihiin tilmaamayaasha farsamada ugu muhiimsan ee hydroxypropyl methylcellulose (HPMC)?

Waxyaabaha ku jira Hydroxypropyl iyo viscosity, isticmaalayaasha badankoodu waxay ka walaacsan yihiin labadan tilmaame.Kuwa leh maadada hydroxypropyl sare waxay guud ahaan leeyihiin haynta biyaha.Midka leh viscosity sare wuxuu leeyahay haynta biyaha ka wanaagsan, xad (aan gabi ahaanba ahayn), iyo kan leh mawjadaha sare ayaa si fiican loogu isticmaalaa hoobiye sibidhka.

2. Waa maxay shaqada ugu weyn ee codsiga HPMC ee budada putty?

Budada suufka ah, HPMC waxay leedahay saddex hawlood oo dhumucdi, haynta biyaha iyo dhismaha.

Dhumucdi: Cellulose waa la dhumucdi karaa si loo laalo oo ay u ilaaliso labbiska kor iyo hoos, oo ay iska caabiso hoos u dhaca.Haysashada biyaha: ka dhig budada suufka si tartiib ah u engejin, oo ka caawi kalsiyamka dambaska in ay ka fal-celiso ficilka biyaha.Dhismaha: Cellulose waxay leedahay saameyn saliideed, taas oo ka dhigi karta budada suufka ah inay leedahay dhismo wanaagsan.

3. Ma jiraa wax xidhiidh ah oo ka dhexeeya dhibicda budada putty iyo HPMC?

Luminta budada budada ah waxay inta badan la xiriirta tayada kaalshiyamka dambaska, wax yarna kuma laha HPMC.Maaddada calcium ee kalsiyum cawl ah iyo saamiga CaO iyo Ca(OH)2 ee kaalshiyam cawl ah kuma habboona, taas oo keeni doonta luminta budada.Haddii ay wax ku leedahay HPMC, ka dibna haynta biyaha ee HPMC waxay sidoo kale keeni doontaa luminta budada.

4. Waa immisa xadiga hydroxypropyl methylcellulose (HPMC) ee budada putty?

Qadarka HPMC ee loo isticmaalo codsiyada la taaban karo way kala duwan tahay iyadoo ku xidhan cimilada, heerkulka, tayada calcium dambaska deegaanka, caanaha budada ah iyo 'tayada looga baahan yahay macaamiisha'.

5. Waa maxay viscosity habboon ee hydroxypropyl methylcellulose (HPMC)?

Guud ahaan, 100,000 yuan oo budo ah ayaa ku filan, shuruudaha hoobiye ayaa sarreeya, 150,000 yuan ayaa loo baahan yahay si sahlan loo isticmaalo.Waxaa intaa dheer, shaqada ugu muhiimsan ee HPMC waa haynta biyaha, oo ay ku xigto dhumucdi.In budada putty, ilaa inta haynta biyuhu ay wanaagsan yihiin iyo viscosity hooseeyo (70,000-80,000), sidoo kale waa suurtogal.Dabcan, mar kasta oo viscosity-ku sarreeyo, way ka sii fiicnaanaysaa haynta biyaha.Marka viscosity-ku dhaafo 100,000, mawgu wax saamayn ah kuma laha haynta biyaha.weyn.

6. Sidee loo doortaa hydroxypropyl methylcellulose (HPMC) ku habboon ujeedooyin kala duwan?

Codsiga budada putty: shuruuduhu way hooseeyaan, viscosity waa 100,000, waa ku filan tahay, waxa muhiimka ah waa in si fiican loo ilaaliyo biyaha.Codsiga hoobiye: shuruudaha sare, viscosity sare, 150,000 ayaa ka fiican, codsiga xabagta: alaabta degdega ah ayaa loo baahan yahay, viscosity sare.

7. Codsiga HPMC ee budada putty, waa maxay sababta goobooyinku ku jiraan budada putty?

Budada suufka ah, HPMC waxay ka ciyaartaa saddex door oo dhumucdi, haynta biyaha iyo dhismaha.Ha ka qayb qaadan wax falcelin ah.Sababaha xumbo:

1. Ku shub biyo badan.

2. Marka lakabka hoose uusan engegin, lakab kale ayaa lagu xoqay dusha sare, wayna fududahay in la xumbo.
