Loluphi usetyenziso oluphambili lwe-hydroxypropyl methylcellulose?
——Impendulo: I-HPMC isetyenziswa kakhulu kwizinto zokwakha, iingubo, iintlaka zokwenziwa, iiseramikhi, amayeza, ukutya, amalaphu, ezolimo, izithambiso, icuba kunye namanye amashishini.I-HPMC inokohlulwa ibe yibakala lokwakha, ibakala lokutya kunye nebakala lamayeza ngokwenjongo.Okwangoku, uninzi lweemveliso zasekhaya zikumgangatho wokwakha.Kwibakala lokwakha, i-putty powder isetyenziswe kwisixa esikhulu, malunga ne-90% isetyenziselwa i-putty powder, kwaye intsalela isetyenziselwa udaka lwesamente kunye neglue.
Uwahlula njani umgangatho we-HPMC ngokulula nangokuqondayo?
——Impendulo: (1) Ubumhlophe: Nangona ubumhlophe bungakwazi ukugqiba ukuba ngaba i-HPMC kulula ukuyisebenzisa, kwaye ukuba i-agent emhlophe yongezwa ngexesha lenkqubo yokuvelisa, iya kuchaphazela umgangatho wayo.Nangona kunjalo, uninzi lweemveliso ezilungileyo zinobumhlophe obuhle.(2) Ukulunga: Ukulunga kwe-HPMC ngokubanzi kune-80 mesh kunye ne-100 mesh, kunye ne-120 mesh ingaphantsi.Uninzi lwe-HPMC eveliswe eHebei yi-80 mesh.Okukhona ukucoleka, xa sithetha ngokubanzi, kungcono.(3) Ukuhanjiswa kokukhanya: faka i-hydroxypropyl methylcellulose (HPMC) emanzini ukwenza i-colloid ebonakalayo, kwaye ujonge ukukhanya kwayo.Okukhona ukuhanjiswa kokukhanya, kungcono, kubonisa ukuba kukho izinto ezinganyibilikiyo kangako kuyo..Ukungena kwereactors ezithe nkqo kulungile, kwaye oko kwereactors ezithe tyaba kubi kakhulu, kodwa ayithethi ukuba umgangatho weereactors ezithe nkqo ungcono kunolo weereactor ezithe tye, kwaye umgangatho wemveliso umiselwa yimiba emininzi.(4) Umxhuzulane okhethekileyo: Okukhona umkhulu umxhuzulane othile, kokukhona unzima ngakumbi.Ubuncinci bukhulu, ngokuqhelekileyo ngenxa yokuba umxholo weqela le-hydroxypropyl kuwo uphezulu, kwaye umxholo weqela le-hydroxypropyl liphezulu, ukugcinwa kwamanzi kungcono.(5) Ukutshisa: Thatha inxalenye encinci yesampuli kwaye uyitshise ngomlilo, kwaye intsalela emhlophe iluthuthu.Izinto ezimhlophe ngakumbi, umgangatho umbi kakhulu, kwaye akukho phantse intsalela kwimpahla ecocekileyo.
Lithini ixabiso le-hydroxypropyl methylcellulose?
—–Impendulo;ixabiso le-hydroxypropylmethyl lixhomekeke kubunyulu bayo kunye nomxholo wothuthu.Ukuphakama kobunyulu, ngaphantsi komxholo womlotha, ixabiso eliphezulu.Ngaphandle koko, ukuhlambuluka okuphantsi, umxholo omlotha ngakumbi, ixabiso eliphantsi.Itoni ukuya kwi-17,000 yeeyuan ngetoni nganye.17,000 yuan yimveliso esulungekileyo phantse akukho ukungcola.Ukuba ixabiso leyunithi liphezulu kune-17,000 yuan, inzuzo yomenzi inyukile.Kulula ukubona ukuba umgangatho ulungile okanye umbi ngokwenani lothuthu kwi-hydroxypropyl methylcellulose.
Yiyiphi i-viscosity ye-hydroxypropyl methylcellulose efanelekileyo kwi-putty powder kunye nodaka?
—–Impendulo;iputty powder iqhele ukuba yi 100,000 yuan, kwaye imfuneko yodaka iphezulu, kwaye idinga 150,000 yeyuan ukuze kube lula ukuyisebenzisa.Ngaphezu koko, owona msebenzi ubalulekileyo we-hydroxypropyl methylcellulose kukugcina amanzi, kulandelwa kukuqina.Kwi-putty powder, ngokude nje ukugcinwa kwamanzi kulungile kwaye i-viscosity iphantsi (70,000-80,000), nayo inokwenzeka.Ngokuqinisekileyo, i-viscosity engaphantsi kwe-100,000 iphezulu, kwaye ukugcinwa kwamanzi okuhambelanayo kungcono.Xa i-viscosity idlula i-100,000, i-viscosity inefuthe ekugcinweni kwamanzi Impembelelo ayinkulu.
