Selelekela:
Putty powder ke thepa ea kaho e sebetsang ka bongata e sebelisoang haholo ho tlatsa masoba, mapetsong le likheo libakeng tse fapaneng tse kang mabota le siling. Leha ho le joalo, e 'ngoe ea litšitiso tsa eona ke ho ba kotsing ea metsi, e ka senyang ts'ebetso ea eona le bophelo bo bolelele. Ho rarolla bothata bona, hydroxypropyl methylcellulose (HPMC) e hlahile e le tlatsetso ea bohlokoa ho matlafatsang ho hanyetsa metsi ha putty powder.
Thepa le Litšobotsi tsa Hydroxypropyl Methylcellulose (HPMC):
Hydroxypropyl methylcellulose, eo hangata e bitsoang HPMC, ke selulose e seng ea ionic e tsoang ho cellulose ea polima ea tlhaho. E entsoe ka etherification ea cellulose, e hlahisang motsoako o nang le thepa e ikhethang e loketseng lits'ebetso tse fapaneng tsa indasteri.
Poloko ea Metsi: HPMC e na le thepa e ntle ea ho boloka metsi, e etsa sebopeho se tsitsitseng se kang gel ha se kopane le metsi. Tšobotsi ena e molemo ho li-putty powder formulations kaha e thusa ho boloka botsitso bo hlokahalang le ho thibela tahlehelo ea metsi nakong ea kopo.
Tlhahiso ea Lifilimi: Ha e omisitsoe, HPMC e etsa filimi e hlakileng le e tenyetsehang holim'a metsi, e fana ka ho hanyetsa metsi ho thepa. Bokhoni bona ba ho etsa filimi bo bohlokoa ho sireletsa phofo ea putty hore e se kenelle mongobo, ka hona e ntlafatsa ho tšoarella ha eona le ts'ebetso ea eona libakeng tse mongobo.
Ho khomarela le ho Kopana: HPMC e ntlafatsa ho khomarela phofo ea putty ho substrate surfaces, ho khothalletsa maqhama a ntlafetseng le ho thibela ho thibela nako ka mor'a nako. Ho feta moo, e ntlafatsa momahano ka har'a matrix a putty, e bakang sebopeho se matla le se momahaneng se hananang le ho kenella ha metsi.
Phetoho ea Rheological: HPMC e sebetsa e le mofetoleli oa rheology, e susumetsang ho phalla le ho sebetsa ha li-putty formulations. Ka ho lokisa viscosity le boitšoaro ba thixotropic, e etsa bonnete ba hore kopo e bonolo ha e ntse e boloka sebopeho se lakatsehang le ho hanyetsa sag.
Kenyelletso ea HPMC ho Liforomo tsa Putty Powder:
Ho kenyelletsoa ha HPMC ho li-putty powder formulations ho kenyelletsa khetho e hlokolosi ea limaraka tse nepahetseng le litekanyetso tsa litekanyetso ho fihlela thepa e lakatsehang ea ho hanyetsa metsi ntle le ho senya likarolo tse ling tsa ts'ebetso. Lintlha tsa bohlokoa li kenyelletsa:
Khetho ea Kereiti: HPMC e fumaneha ka limaraka tse fapaneng ka viscosity e fapaneng, degree ea substitution, le kabo ea boholo ba likaroloana. Khetho ea kereiti e nepahetseng e ipapisitse le lintlha tse joalo ka litlhoko tsa ts'ebeliso, boemo bo lakatsehang ba ho hanyetsa metsi, le ho lumellana le litlatsetso tse ling.
Ntlafatso ea Tekanyo: Tekanyo e nepahetseng ea HPMC ka li-putty powder formulations e itšetlehile ka lintlha tse 'maloa, ho kenyelletsa le kopo e khethehileng, sebopeho sa sebopeho, le litšoaneleho tsa ts'ebetso tse lakatsehang. Likahare tse fetelletseng tsa HPMC li ka lebisa ho li-viscosity buildup le mathata ts'ebelisong, athe tekanyetso e sa lekaneng e ka baka ho se lekane ha metsi.
Ho lumellana le Li-additives: HPMC e lumellana le mefuta e mengata ea li-additives tse atisang ho sebelisoa ha ho etsoa li-putty formulations, ho kenyelletsa le li-thickeners, dispersants, le li-preservatives. Teko ea ho lumellana e bohlokoa ho netefatsa botsitso le katleho ea tlhahiso ea ho qetela ntle le ho baka tšebelisano e mpe kapa mathata a ts'ebetso.
Mokhoa oa ho Kopanya: Phatlalatso e nepahetseng ea HPMC ka har'a matrix a putty powder ke ea bohlokoa ho netefatsa ho ts'oana le katleho. E atisa ho qhalakanngoa ka metsing 'me butle-butle e eketsoa likarolong tsa phofo ha e ntse e kopanya ho finyella kabo ea homogeneous le ho qoba agglomeration.
Melemo ea HPMC ho Putty Powder e Thibelang Metsi:
Ho kenyelletsoa ha HPMC ho fana ka melemo e 'maloa ho ntlafatsa ho hanyetsa metsi ha putty powder, ho kenyelletsa:
Ntlafatso ea ho tšoarella nako e telele: HPMC e theha tšitiso e sirelletsang khahlano le ho kenella ha mongobo, ka hona e ntlafatsa ho tšoarella le bophelo bo bolelele ba li-putty libakeng tse mongobo joalo ka likamore tsa ho hlapela le kichine.
Ho Fokotsa ho Petsoha le ho Shrinkage: Thepa e ntlafalitsoeng ea momahano le mamaretso ea HPMC e fokotsa ho phatloha le ho honyela ha li-putty layers, ho netefatsa pheletso e boreleli le e se nang moeli ha nako e ntse e ea.
Matla a Ntlafetseng a ho sebetsa: HPMC e ntlafatsa ho sebetsa le ho hasana ha li-putty formulations, e lumellang hore ho be bonolo ho sebetsa le ho qeta bokaholimo bo bonolo.
Ho feto-fetoha ha maemo: HPMC e ka sebelisoa hammoho le li-additives tse ling ho hlophisa thepa ea li-putty formulations ho latela litlhoko tse khethehileng tsa kopo, tse kang ho fetoha ha maemo, matla, kapa ho hanyetsa hlobo.
Lisebelisoa tsa Putty Powder e Thibela Metsi:
Phofo e sa keneleng metsi e kenyelletsang HPMC e fumana lits'ebetso tse fapaneng mererong ea kaho ea bolulo le ea khoebo, ho kenyelletsa:
Litokiso tsa Lerako la ka Hare: Phofo e nang le metsi e matlafalitsoeng e loketse ho lokisoa le ho pata mabota a kahare, haholo libakeng tse pepesehang mongobo joalo ka likamore tsa ho hlapela, kichine le likamore tsa ho hlatsoetsa.
Kantle ho Qetello ea Bokahohle: Metsoako e sa keneleng metsi ea li-putty e loketse lisebelisoa tsa ka ntle tsa ho qetela, e fana ka tšireletso khahlanong le pula, mongobo le litšila tsa tikoloho.
Tile Grouting: HPMC-modified putty powders e sebelisoa bakeng sa lisebelisoa tsa lithaele tsa grouting, ho netefatsa hore ho khomarela ka matla, ho hanyetsa metsi, le ho hanyetsa mapheo libakeng tse metsi tse kang lipula, matamo a ho sesa le mathule.
Mokhabiso oa Mould: Putty phofo e nang le li-additives tsa HPMC e sebelisoa bakeng sa ho bōpa mokhabiso le lits'ebetso tsa ho betla, tse fanang ka ho hanyetsa hlobo le botsitso ba sebopeho maemong a mongobo.
Hydroxypropyl methylcellulose (HPMC) e bapala karolo ea bohlokoa ho ntlafatse khanyetso ea metsi ea li-putty powder formulations, ho fana ka thepa e ntlafetseng ea ho tšoarella, ho khomarela le ho sebetsa. Ka ho kenyelletsa HPMC ho li-putty formulations, litsebi tsa kaho li ka fihlela ts'ebetso e phahameng le ho phela nako e telele lits'ebetsong tse fapaneng tsa kahare le kantle tse tlas'a khatello ea mongobo. Boiteko bo eketsehileng ba lipatlisiso le nts'etsopele bo loketse ho lekola litlhophiso tse tsoetseng pele le ho ntlafatsa maemo a litekanyetso tsa HPMC bakeng sa litlhoko tse ikhethileng tsa kaho, ka hona ho nts'etsapele boemo ba morao-rao ba theknoloji ea putty e thibelang metsi.
