Li-powders tsa HPMC tsa boemo ba meralo li ntse li tsebahala indastering ea kaho, haholo bakeng sa li-primers. HPMC (Hydroxypropylmethylcellulose) ke motsoako oa selulose o nkiloeng ho makhasi a lehong a sebelisoang haholo liindastering tse fapaneng ho kenyeletsoa indasteri ea kaho ka lebaka la ho feto-fetoha ha eona le thepa e ntle haholo. Sehloohong sena, re tšohla melemo e fapaneng ea ho sebelisa li-powders tsa HPMC tsa meralo ho li-primers.
1. Ho boloka metsi ka mokhoa o babatsehang
E 'ngoe ea melemo ea bohlokoa ka ho fetisisa ea ho sebelisa phofo ea HPMC ho li-primers ke thepa ea eona e ntle ea ho boloka metsi. HPMC phofo e ka monya mongobo ka potlako 'me ea e boloka ka sebopeho sa eona, kahoo e lelefatsa nako ea ho beha primer le ho eketsa matla a ho kopanya pakeng tsa substrate le topcoat. Thepa ena e bohlokoa ka ho khetheha ha ho phekoloa libaka tse nang le li-porous kaha e thusa ho thibela primer ho kena ka har'a substrate le ho ntlafatsa ho khomarela.
2. Ntlafatsa mokhoa oa ho sebetsa
Mehaho ea HPMC phofo ea meralo e thusa ho ntlafatsa thepa ea kopo ea primer. Ho eketsa phofo ea HPMC ho primer ho tla eketsa viscosity bakeng sa kopo e bonolo. Thepa ena e tiisa hore primer e hasana ka mokhoa o ts'oanang 'me e etsa sebaka se boreleli, se bohlokoa bakeng sa ho qeta boleng bo phahameng. Ho feta moo, e thusa ho fokotsa ho hlaha ha marotholi a sa batleheng le ho thusa ho felisa tlhokahalo ea lehlabathe le feteletseng kapa boreleli.
3. Ntlafatsa ho khomarela
Monyetla o mong o moholo oa li-powders tsa HPMC ho li-primers ke bokhoni ba tsona ba ho ntlafatsa ho khomarela. Li-primers tse entsoeng ka phofo ea HPMC li na le sekhomaretsi se setle ho li-substrates tse fapaneng tse kenyelletsang konkreite, lehong le tšepe. Ho khomarela hona ho ntlafetseng ho bakoa ke thepa ea ho kopanya sefapano e teng ka phofo ea HPMC, e etsang hore ho be le maqhama pakeng tsa substrate le topcoat. Tšobotsi ena e thusa ho etsa bonnete ba hore topcoat e khomarela ka thata ho primer bakeng sa qetello ea nako e telele, e tšoarellang.
4. Ntlafatso ea nako e telele
Meaho ea HPMC phofo ea meralo e boetse e thusa ho ntlafatsa ho tšoarella ha primer. HPMC phofo e na le metsi a mangata, hlobo le lik'hemik'hale, e sireletsa li-primers ho tloha ho senyeha. Ho feta moo, li-powders tsa HPMC li boetse li tsejoa ka ho hanyetsa boemo ba leholimo bo botle, e leng se etsang hore e be tse loketseng bakeng sa ho sebelisoa ho li-primers tsa ka ntle. Tšobotsi ena e tiisa hore primer e tla lula e tiile esita le maemong a leholimo a thata, qetellong e thusa ho lelefatsa bophelo ba topcoat.
5. Ho bonolo ho kopanya
Molemo o mong oa bohlokoa oa li-powders tsa HPMC ho li-primers ke boiketlo ba tsona ba ho kopanya. Li-powders tsa HPMC li qhibiliha ka metsing, e leng se etsang hore li qhibilihe habonolo ka metsing ebe li etsa motsoako oa homogeneous. Bokhoni ba ho hlahisa motsoako oa homogeneous bo tiisa hore primer e tsitsitse le hore motsoako o tšoanang o sebelisoa holim'a metsi kaofela. Ho phaella moo, phofo ea HPMC e thibela ho thehoa ha maqhubu, ho etsa bonnete ba hore primer e lula e boreleli ebile e lekana.
6. Ts'ebetso e phahameng ea litšenyehelo
Bakeng sa lik'hamphani tsa kaho, tšebeliso ea li-powders tsa HPMC tsa meralo ho li-primers ke tharollo e theko e boima. HPMC phofo e theko e tlaase, e fumaneha habonolo, 'me e hloka chelete e nyenyane feela ho finyella phello e lakatsehang. Sena se bolela hore lik'hamphani tsa kaho li boloka chelete, e leng se qetellang se thusa ho fokotsa litšenyehelo tsa morero.
7. Tšireletso ea tikoloho
Qetellong, o mong oa melemo ea bohlokoa ka ho fetisisa ea ho sebelisa phofo ea HPMC ho li-primers ke hore li na le botsoalle ba tikoloho. HPMC phofo e entsoe ka selulose, mohloli o tsosolositsoeng. Ho feta moo, li ka senyeha habonolo, ho bolelang hore li senyeha habonolo 'me li ke ke tsa senya tikoloho. Ho sebelisa phofo ea HPMC ho fokotsa khabone ea merero ea kaho, ho e etsa khetho e tsitsitseng le e nang le boikarabelo.
Ts'ebeliso ea li-powders tsa HPMC tsa boemo ba meralo ho li-primers ke khetho e ntle bakeng sa lik'hamphani tsa kaho. Li-powders tsa HPMC li fana ka mefuta e mengata ea melemo e kenyelletsang ho boloka metsi ka mokhoa o babatsehang, ts'ebetso e ntlafetseng, ho khomarela ho ntlafatsa, ho ntlafatsa nako e telele, ho kopanya habonolo, ho boloka litšenyehelo le ho tšoarella. Thepa ena e etsa hore phofo ea HPMC e be khetho e nepahetseng bakeng sa merero ea kaho e hlokang primer ea boleng bo holimo bakeng sa pheletso e tšoarellang nako e telele.
