Tinoziva kuti hydroxypropyl methylcellulose chinhu chine hupfu kana chiri patembiricha yemumba, uye hupfu hwacho hwakafanana, asi kana ukahuisa mumvura, mvura yacho inova yakakora panguva ino. Uye nechiyero chakati che viscosity, tinogona kuiona nemazvo nekushandisa hunhu hwehydroxypropyl methylcellulose, uye nzvimbo dzakawanda dzekuvaka dzichawanzoenderana nehunhu hwakadaro hwayo, rega hupfu hwasara hwe putty husanganiswe kuti huwedzere kunamira pakati pehupfu hwe putty nepamusoro pemadziro, saka ndeapi mamwe mashoko anofanira kutariswa paunenge uchiisa hydroxypropyl methylcellulose kuhupfu hwe putty?
Kana hupfu hwacho hwagadzirwa, panofanira kunge paine chinodiwa chemushonga, uye kushandiswa kwehydroxypropyl methylcellulose hakuna kusiyana. Pakugadzira mushonga wakasanganiswa neputty powder, muyero wawo unowanzoenderana nekupisa kwekunze, nharaunda, Hunhu hwecalcium yemuno hunoenderana zvakanyanya nezvinhu izvi. Kazhinji, mimwe mishonga yeputty powder inofanira kugadzirwa. Kazhinji, vanhu vanoshandisa hydroxypropyl methylcellulose iri pakati pe4 kg ne5 kg, asi kazhinji huwandu hunoshandiswa munguva yechando hwakakwira pane hwemuzhizha. Hunofanira kunge hushoma. Paunogadzira mushonga wakasanganiswa, unogona kuupfupikisa nokungwarira.
Uyezve, kana musanganiswa wemusanganiswa wagadzirwa munzvimbo dzakasiyana, chiyero chinosiyanawo. Semuenzaniso, kugadzirira musanganiswa munzvimbo yakati yeBeijing, zvinowanzodiwa kuwedzera 5 kg yeHPMC. Asi huwandu uhwu hunoshandiswawo muzhizha, uye 0.5 kg shoma munguva yechando; asi munzvimbo dzakadai seYunnan, pakugadzira musanganiswa, kazhinji kunongoda kuisa 3 kg - 4 kg yeHPMC, chiyero chacho chishoma pane cheBeijing, uye nharaunda yacho yakasiyana, uye pachava nemusiyano muhuwandu hwechisikigo.
