Waa maxay isticmaalka ugu muhiimsan ee hydroxypropyl methylcellulose?
——Jawab: HPMC waxa si weyn loogu isticmaalaa agabka dhismaha, dahaarka, resins synthetic, ceramics, dawooyinka, cuntada, dunta, beeraha, qurxinta, tubaakada iyo warshadaha kale. HPMC waxa loo qaybin karaa darajada dhismaha, heerka cuntada iyo darajada dawooyinka iyadoo loo eegayo ujeedada. Waqtigan xaadirka ah, badi wax soo saarka gudaha waa heerka dhismaha. Marka la eego heerka dhismaha, budada putty waxaa loo isticmaalaa xaddi badan, qiyaastii 90% waxaa loo isticmaalaa budada shubka, inta soo hartayna waxaa loo isticmaalaa hoobiye sibidhka iyo xabagta.
Sidee loo kala saaraa tayada HPMC si fudud oo dareen leh?
——Jawab: (1) Caddaan: In kasta oo aan caddaanku go’aamin karin in HPMC ay fududahay in la isticmaalo iyo in kale, iyo haddii wax lagu caddeeyo inta lagu jiro habka wax-soo-saarka, waxay saamaynaysaa tayada. Si kastaba ha noqotee, badi alaabooyinka wanaagsan waxay leeyihiin caddaan wanaagsan. (2) Wanaagsanaanta: Wanaajinta HPMC guud ahaan waxay leedahay 80 mesh iyo 100 mesh, iyo 120 mesh ayaa ka yar. Inta badan HPMC ee laga soo saaro Hebei waa 80 mesh. Sida ugu fiican ee ganaaxa, guud ahaan marka loo eego, ayaa ka sii wanaagsan. (3) Gudbinta fudud: geli hydroxypropyl methylcellulose (HPMC) biyaha si ay u sameeyaan kolloid hufan, oo fiiri gudbintiisa iftiinka. Sida weyn ee gudbinta iftiinka, ayaa ka sii wanaagsan, taas oo muujinaysa in ay jiraan waxyaabo aan milmi karin oo ku jira. . Dareen-celinta reactors toosan guud ahaan waa wanaagsan tahay, iyo tan reactors-ka jiifka ah ayaa ka sii daran, laakiin macnaheedu maaha in tayada reactors-ka toosan ay ka wanaagsan tahay reactors-ka tooska ah, tayada wax soo saarkana waxaa lagu go'aamiyaa arrimo badan. (4) Cufisjiid gaar ah: Markasta oo uu weynaado cufisjiidka gaarka ah, waa uu sii cuslaaday. Gaar ahaan waa weyn yahay, guud ahaan sababtoo ah waxa ku jira kooxda hydroxypropyl ee ku jira waa sarreeyaa, iyo waxa ku jira kooxda hydroxypropyl waa sarreeyaa, haynta biyaha ayaa ka fiican. (5) Gubasho: Qaado qayb yar oo ka mid ah muunada oo ku shid dab, inta cad ee soo hadhayna waa dambas. Walxaha badan ee cadaanka ah, tayada ayaa ka sii dareysa, mana jiraan ku dhawaad wax hadhaaga ah ee alaabta saafiga ah.
Waa maxay qiimaha hydroxypropyl methylcellulose?
—–Jawaab; Qiimaha hydroxypropylmethyl waxay kuxirantahay nadiifnimadeeda iyo waxa ku jira dambaska. Mar kasta oo nadiifnimadu ay sarrayso, waxa ka yar dambaska ku jira, qiimaha sarreeya. Haddii kale, nadiifnimada hoose, inta ka kooban dambaska, hoos ayuu u dhigayaa qiimaha. Tan ilaa 17,000 yuan halkii ton. 17,000 yuan waa badeecad saafi ah oo aan wax wasakh ah lahayn. Haddii qiimaha cutubku ka sarreeyo 17,000 yuan, faa'iidada soo saaraha ayaa kordhay. Way fududahay in la arko in tayadiisu wanaagsan tahay ama ay xun tahay iyadoo loo eegayo qaddarka dambaska ee hydroxypropyl methylcellulose.
Waa maxay viscosity of hydroxypropyl methylcellulose ee ku habboon budada putty iyo hoobiye?
—–Jawaab; budada putty guud ahaan waa 100,000 yuan, sharuuda hoobiyena waa ka badan tahay, waxayna u baahan tahay 150,000 yuan si ay u sahlanaato isticmaalka. Waxaa intaa dheer, shaqada ugu muhiimsan ee hydroxypropyl methylcellulose 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, viscosity ka hooseeya 100,000 waa ka sarreeyaa, haynta biyaha ee qaraabada ah ayaa ka fiican. Marka viscosity-ku dhaafo 100,000, majiishu waxay saameyn ku yeelataa haynta biyaha Saameyntu maaha mid weyn.
