Ikuphi ukusetshenziswa okuyinhloko kwe-hydroxypropyl methylcellulose?
——Impendulo: I-HPMC isetshenziswa kakhulu ezintweni zokwakha, okokuhlanganisa, ama-synthetic resin, izitsha zobumba, imithi, ukudla, izindwangu, ezolimo, izimonyo, ugwayi nezinye izimboni. I-HPMC ingahlukaniswa ngebanga lokwakha, ibanga lokudla kanye nebanga lezemithi ngokwenhloso. Njengamanje, iningi lemikhiqizo yasekhaya isezingeni lokwakha. Ebangeni lokwakha, i-putty powder isetshenziswa ngenani elikhulu, cishe i-90% isetshenziselwa i-putty powder, kanti enye isetshenziselwa udaka lukasimende neglue.
Indlela yokuhlukanisa ikhwalithi ye-HPMC kalula nangokunembile?
——Impendulo: (1) Ubumhlophe: Nakuba ubumhlophe bungakwazi ukunquma ukuthi i-HPMC kulula yini ukuyisebenzisa, futhi uma ama-ejenti amhlophe engezwa phakathi nenqubo yokukhiqiza, izothinta ikhwalithi yayo. Nokho, iningi lemikhiqizo emihle inobumhlophe obuhle. (2) Ubuhle: Ubucwebe be-HPMC ngokuvamile buba ne-80 mesh kanye ne-100 mesh, kanye ne-120 mesh mincane. Iningi le-HPMC elikhiqizwe e-Hebei linezikhala ezingama-80. Ubuhle obuhle, uma sikhuluma nje, kuba ngcono. (3) Ukudlulisa ukukhanya: faka i-hydroxypropyl methylcellulose (HPMC) emanzini ukuze wenze i-colloid ekhanyelayo, bese ubheka ukudlulisa ukukhanya kwayo. Ukudlulisa ukukhanya okukhulu, kungcono, okubonisa ukuthi kukhona okuncane okungancibiliki kuwo. . Ukufinyeleleka kwama-reactor aqondile ngokuvamile kuhle, futhi lokho kwama-reactor avundlile kubi kakhulu, kodwa akusho ukuthi ikhwalithi yama-reactor aqondile ingcono kunaleyo yama-reactor avundlile, futhi ikhwalithi yomkhiqizo inqunywa izici eziningi. (4) Amandla adonsela phansi athize: Uma umkhulu amandla adonsela phansi athile, uyasinda kakhulu. Ukucaciswa kukhulu, ngokuvamile ngenxa yokuthi okuqukethwe kweqembu le-hydroxypropyl kulo kuphezulu, futhi okuqukethwe kweqembu le-hydroxypropyl kuphezulu, ukugcinwa kwamanzi kungcono. (5) Ukushiswa: Thatha ingxenye encane yesampula uyithungele ngomlilo, futhi insalela emhlophe ibe umlotha. I-substance emhlophe eyengeziwe, ikhwalithi iba yimbi kakhulu, futhi cishe akukho zinsalela ezimpahleni ezihlanzekile.
Iyini intengo ye-hydroxypropyl methylcellulose?
—–Impendulo; intengo ye-hydroxypropylmethyl incike ekuhlanzekeni kwayo kanye nokuqukethwe komlotha. Ukuphakama kokuhlanzeka, ukuncipha komlotha, intengo ephezulu. Uma kungenjalo, ukuhlanzeka okuphansi, umlotha omningi, intengo iyancipha. Ithani ukuya ku-17,000 yuan ngethani. I-17,000 yuan iwumkhiqizo omsulwa ongenakho ukungcola cishe. Uma intengo yeyunithi ingaphezulu kuka-17,000 yuan, inzuzo yomkhiqizi inyukile. Kulula ukubona ukuthi izinga lihle noma libi ngokwenani lomlotha ku-hydroxypropyl methylcellulose.
Iyiphi i-viscosity ye-hydroxypropyl methylcellulose efanelekile i-putty powder nodaka?
—–Impendulo; i-putty powder ivamise ukuba ngu-100,000 yuan, futhi imfuneko yodaka iphezulu, futhi idinga amayuan angu-150,000 ukuze kube lula ukuyisebenzisa. Ngaphezu kwalokho, umsebenzi obaluleke kakhulu we-hydroxypropyl methylcellulose ukugcinwa kwamanzi, okulandelwa ukujiya. Ku-putty powder, inqobo nje uma ukugcinwa kwamanzi kuhle futhi i-viscosity iphansi (70,000-80,000), kungenzeka futhi. Yiqiniso, i-viscosity engaphansi kwe-100,000 iphakeme, futhi ukugcinwa kwamanzi okuhlobene kungcono. Uma i-viscosity idlula i-100,000, i-viscosity inomthelela ekugcineni amanzi Umthelela awumkhulu.
