Architectural giredhi HPMC poda iri kuwana mukurumbira muindasitiri yekuvaka, kunyanya kune yekutanga. HPMC (Hydroxypropylmethylcellulose) ndeye cellulose inotorwa kubva muhuni pulp iyo inoshandiswa zvakanyanya mumaindasitiri akasiyana siyana anosanganisira indasitiri yekuvaka nekuda kwekuita kwayo uye nekunaka zvivakwa. Muchinyorwa chino, tinokurukura mabhenefiti akasiyana ekushandisa ekuvakisa giredhi HPMC hupfu mumaprimers.
1. Yakanakisa kuchengetedza mvura
Imwe yemabhenefiti akakosha ekushandisa HPMC poda mumaprimers ndiyo yakanakisa kuchengetedza mvura. HPMC poda inogona kukurumidza kutora unyoro uye kuichengeta muhutano hwayo, nokudaro kuwedzera nguva yekuisa yekutanga uye kuwedzera simba rekubatanidza pakati pe substrate uye topcoat. Ichi chivakwa chinonyanya kukosha pakurapa porous nzvimbo sezvo ichibatsira kudzivirira iyo primer kubva ichipinda mu substrate uye inosimudzira kunamatira.
2. Kuvandudza kushanda
Architectural giredhi HPMC poda inobatsira kuvandudza zvimiro zvekushandisa zveprimer. Kuwedzera HPMC poda kune yekutanga kuchawedzera viscosity kuitira nyore kushandisa. Ichi chivakwa chinovimbisa kuti primer inopararira zvakaenzana uye inogadzira nzvimbo yakatsetseka, iyo yakakosha pakupedza kwemhando yepamusoro. Uyezve, inobatsira kuderedza kuitika kwemadrip asingadiwe uye inobatsira kubvisa kudiwa kwejecha rakawandisa kana kutsvedzerera.
3. Kuwedzera kunamatira
Imwe mukana mukuru weHPMC poda mumaprimers kugona kwavo kusimudzira kunamatira. Maprimers akagadzirwa kubva kuHPMC poda ane yakanakisa kunamatira kune akasiyana ma substrates anosanganisira kongiri, huni nesimbi. Uku kunamatira kwakakwidziridzwa kunokonzerwa nekuchinjika-kubatanidza zvivakwa zviripo muHPMC poda, izvo zvinogadzira chisungo pakati pe substrate uye topcoat. Iyi ficha inobatsira kuve nechokwadi chekuti topcoat inonamira zvakasimba kune yekutanga kwenguva refu, yakasimba kupera.
4. Kuvandudza kusimba
Architectural giredhi HPMC poda inobatsirawo kusimbisa kusimba kweiyo primer. HPMC hupfu ine mvura yakawanda, ukuvhu uye inodzivirira kemikari, inodzivirira maprimers kubva mukuora. Pamusoro pezvo, HPMC hupfu dzinozivikanwawo nekunaka kwemamiriro ekunze, izvo zvinoita kuti dzive dzakanakira kushandiswa mune zvekunze zvekutanga. Iyi ficha inovimbisa kuti primer icharamba yakasimba kunyangwe mumamiriro ekunze akaomarara, pakupedzisira ichibatsira kuwedzera hupenyu hwetopcoat.
5. Nyore kusanganisa
Imwe mukana wakakosha weHPMC poda mumaprimers ndiko kusununguka kwavo kwekusanganisa. HPMC hupfu vari mvura soluble, izvo zvinoita kuti vanyunguduke nyore mumvura uye kuumba homogeneous musanganiswa. Iko kugona kugadzira musanganiswa wehomogeneous inovimbisa kuti iyo primer inopindirana uye kuti iyo yakafanana kuumbwa inoiswa kune yese nzvimbo. Mukuwedzera, HPMC poda inodzivirira kuumbwa kwemapundu, kuve nechokwadi kuti iyo primer inoramba yakatsetseka uye kunyange.
6. Kuita mari yepamusoro
Kune makambani ekuvaka, kushandiswa kwegiredhi yekuvaka HPMC poda mumaprimers mhinduro inodhura. HPMC poda inokwanisika, inowanikwa zviri nyore, uye inoda chete mari shoma kuti iwane mhedzisiro yaunoda. Izvi zvinoreva kuti makambani ekuvaka anochengetedza mari, izvo zvinozobatsira kuderedza mari yeprojekiti.
7. Kuchengetedzwa kwezvakatipoteredza
Chekupedzisira, imwe yemabhenefiti akakosha ekushandisa HPMC hupfu mumaprimers ndeyekuti vane hushamwari kwezvakatipoteredza. HPMC poda inogadzirwa kubva ku cellulose, chinhu chinogonekazve. Uyezve, iwo anodedera, zvichireva kuti anoputsika nyore uye haakuvadze nharaunda. Kushandisa HPMC poda kunoderedza kabhoni tsoka yemapurojekiti ekuvaka, zvichiita kuti ive sarudzo yakagadzikana uye ine mutoro.
Iko kushandiswa kwegiredhi yekuvaka HPMC poda mumaprimers isarudzo yakanakisa kumakambani ekuvaka. HPMC hupfu hunopa huwandu hwakawanda hwemabhenefiti anosanganisira yakanakisa kuchengetedza kwemvura, yakagadziridzwa kugadziridzwa, yakasimbiswa adhesion, yakagadziridzwa kusimba, nyore kusanganisa, kudhura-kugona uye kusimba. Izvi zvivakwa zvinoita kuti HPMC hupfu ive sarudzo yakanakira mapurojekiti ekuvaka anoda yemhando yepamusoro primer yekupedzisa kwenguva refu.
