Yintoni eyona nto isetyenziswa kakhulu yi-hydroxypropyl methylcellulose?
——Impendulo:I-HPMCIsetyenziswa kakhulu kwizixhobo zokwakha, iipeyinti, iiresini zokwenziwa, iiseramikhi, amayeza, ukutya, amalaphu, ezolimo, izinto zokuthambisa, icuba kunye namanye amashishini. I-HPMC inokwahlulwa ibe yinqanaba lokwakha, izinga lokutya kunye nenqanaba leyeza ngokwenjongo. Okwangoku, uninzi lweemveliso zasekhaya zinqanaba lokwakha. Kwinqanaba lokwakha, umgubo we-putty usetyenziswa kakhulu, malunga ne-90% isetyenziselwa umgubo we-putty, kwaye okuseleyo kusetyenziselwa udoti wesamente kunye neglu.
Indlela yokwahlula umgangatho we-HPMC ngokulula nangokungacwangciswanga?
——Impendulo: (1) Ubumhlophe: Nangona ubumhlophe bungenakukwazi ukumisela ukuba kulula na ukusebenzisa i-HPMC, kwaye ukuba ii-agents zokwenza mhlophe zongezwa ngexesha lenkqubo yemveliso, ziya kuchaphazela umgangatho wayo. Nangona kunjalo, uninzi lweemveliso ezilungileyo zinobumhlophe obuhle. (2) Ubumhlophe: Ubumhlophe be-HPMC ngokubanzi bune-mesh engama-80 kunye ne-100 mesh, kwaye i-120 mesh incinci. Uninzi lwe-HPMC eveliswa eHebei yi-80 mesh. Okukhona ubumhlophe buncinci, ngokubanzi, kokukhona kungcono. (3) Ukuhanjiswa kokukhanya: faka i-hydroxypropyl methylcellulose (HPMC) emanzini ukuze wenze i-colloid ecacileyo, kwaye ujonge ukuhanjiswa kokukhanya kwayo. Okukhona ukuhanjiswa kokukhanya kukhulu, kokukhona kungcono, okubonisa ukuba akukho nto inganyibilikiyo kuyo. . Ukuvuleka kwee-reactors ezithe nkqo kudla ngokuba kuhle, kwaye oko kwee-reactors ezithe nkqo kubi, kodwa akuthethi ukuba umgangatho wee-reactors ezithe nkqo ungcono kunowee-reactors ezithe nkqo, kwaye umgangatho wemveliso umiselwa zizinto ezininzi. (4) Ubumhlophe obuthile: Okukhona ububunzima obuthile bukhulu, kokukhona ubunzima bungcono. Ubungakanani bukhulu, ngokubanzi kuba umxholo weqela le-hydroxypropyl kuyo uphezulu, kwaye umxholo weqela le-hydroxypropyl uphezulu, ukugcinwa kwamanzi kungcono. (5) Ukutsha: Thatha inxalenye encinci yesampulu uze uyitshise ngomlilo, kwaye intsalela emhlophe iba luthuthu. Okukhona into emhlophe ininzi, kokukhona umgangatho wayo usiba mbi, kwaye akukho ntsalela phantse kwizinto ezicocekileyo.
Ixabiso le-hydroxypropyl methylcellulose lingakanani?
—–Impendulo; ixabiso le-hydroxypropylmethyl lixhomekeke kubunyulu bayo kunye nomxholo wothuthu. Okukhona ubunyulu buphezulu, kokukhona umxholo wothuthu uphantsi, kokukhona ixabiso liphezulu. Ngaphandle koko, okukhona ubunyulu buphantsi, kokukhona umxholo wothuthu ungaphezulu, kokukhona ixabiso liphantsi. I-Ton ukuya kwi-17,000 yuan ngetoni. I-17,000 yuan yimveliso ecocekileyo engenazo zonke izinto ezingcolileyo. Ukuba ixabiso leyunithi liphezulu kune-17,000 yuan, inzuzo yomenzi inyukile. Kulula ukubona ukuba umgangatho ulungile okanye umbi ngokwenani lothuthu kwi-hydroxypropyl methylcellulose.
Yeyiphi i-viscosity ye-hydroxypropyl methylcellulose efanelekileyo kwi-putty powder kunye ne-mortar?
—–Impendulo; umgubo we-putty uhlala uxabisa i-100,000 yuan, kwaye imfuneko yodaka iphezulu, kwaye ifuna i-150,000 yuan ukuze kube lula ukuyisebenzisa. Ngaphezu koko, owona msebenzi ubalulekileyoi-hydroxypropyl methylcellulosekukugcinwa kwamanzi, kulandele ukuqina. Kwi-putty powder, lo gama nje ukugcina amanzi kulungile kwaye i-viscosity iphantsi (70,000-80,000), kunokwenzeka. Kakade ke, i-viscosity engaphantsi kwe-100,000 iphezulu, kwaye ukugcinwa kwamanzi okufanelekileyo kungcono. Xa i-viscosity idlula i-100,000, i-viscosity inefuthe ekugcinweni kwamanzi. Impembelelo ayibi ntle.
