Shaqada hydroxypropyl methylcellulose (HPMC) ee gidaarka

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.Dhisidda: Cellulose waxay leedahay saameyn saliideed, taas oo ka dhigi karta budada putty 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 maxay tiradahydroxypropyl methylcellulose (HPMC) oo ku jira derbigabudo?
Qadarka HPMC ee loo isticmaalo codsiyada wax ku oolka ah way kala duwan tahay iyadoo ku xidhan cimilada, heerkulka, tayada calcium dambaska deegaanka, caanaha budada putty iyo "tayada loo baahan yahay macaamiisha".Guud ahaan, inta u dhaxaysa 4 kg ilaa 5 kg.Tusaale ahaan: inta badan budada putty ee Beijing waa 5 kg;Inta badan budada putty ee Guizhou waa 5 kg xagaaga iyo 4.5 kg xilliga qaboobaha;Qadarka putty ee Yunnan waa mid yar, guud ahaan 3 kg ilaa 4 kg, iwm.

5. Waa maxay viscosity habboon ee hydroxypropyl methylcellulose (HPMC)?
Guud ahaan, 100,000 yuan oo budo ah ayaa ku filan, shuruudaha hoobiye ayaa ka 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 iyo inta haynta biyuhu ay wanaagsan yihiin iyo viscosity hooseeyo (70,000-80,000), sidoo kale waa suurtogal.Dabcan, mar kasta oo viscosity-ku sarreeyo, ayaa si fiican u sii haynta biyaha.Marka viscosity-ku dhaafo 100,000, majiishu 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 qaybgelin wax falcelin ah.Sababaha xumbo:
(1) Ku shub biyo badan.
(2) Lakabka hoose ma qallajin, lakab kale ayaa lagu xoqay dusha sare, wayna fududahay in la xumbo.
