HPMC (hydroxypropyl methylcellulose) ine huwandu hwakawanda hwemashandisirwo mumaindasitiri ekukoira uye pendi. Semushonga wepolymer, unogona kunyatso kuvandudza zvimiro zvemuviri uye kushandisa mhedzisiro yejasi nependi.
1. Thickeners uye rheology control agents
HPMC ine yakanaka thickening maitiro. Mumaindasitiri machira uye pendi, HPMC inogona zvakanyanya kuwedzera viscosity uye kuwedzera rheology yejasi. Uku kukora kunobatsira kudzora kuyerera uye kugadzikana kwepende panguva yekushandisa, zvichiita kuti zvive nyore kuisa uye kugovera zvakaenzana. Kunyanya kana kupenda ma facade, HPMC inogona kudzivirira pendi kubva pakudonha, kuvandudza kushanda, uye kuve nechokwadi kupfava uye kufanana kwejasi.
HPMC ine yakasarudzika kugona kugadzirisa rheology yejasi, ichivabvumira kuratidza pseudoplastic kuyerera maitiro. Izvi zvinoreva kuti pasi pekugera (senge kana kupenda kana kupfapfaidza), viscosity yepende inoderera, zvichiita kuti zvive nyore kuisa, uye kana pakuzorora, viscosity inodzoka kudzivirira kudonha kana kudonha.
2. Mafirimu-kugadzira zvinowedzera
HPMC ine yakanaka yekugadzira firimu zvinhu, izvo zvinoita kuti ive yakakosha seyakagadziriswa firimu rekuwedzera mune coating uye pendi. HPMC inogona kushanda pamwe chete nezvimwe zvinhu zvekugadzira firimu kugadzira yunifomu uye dense coating film. Uku kupfekedza kunogona kukwidziridza kunamira kwejasi uye kudzivirira kutsemuka uye kusvuuka, nekudaro ichivandudza kusimba uye kukanganisa kuramba kwejasi. Pamusoro pezvo, HPMC inogona zvakare kuvandudza kudzivirira kwemvura kwejasi, kuderedza kukonzeresa kwehunyoro pafirimu yekuputira, uye kuwedzera hupenyu hwebasa rejasi.
3. Moisturizer uye anti-skin effect
HPMC ine yakanakisa moisturizing zvimiro, izvo zvinotora basa rakakosha mukuwomeswa kwemaindasitiri machira. Paunenge uchiisa pendi, kuchengetedza hunyoro hwakakodzera uye kuwedzera nguva yekuomeswa kunogona kubatsira kuve nechokwadi chekushanda kwakatsetseka uye kunyange kuomeswa kwepende, kuderedza mukana wekutsemuka kana mabhuru. Kunyanya munzvimbo dzinopisa kana dzakaoma, HPMC inogona kudzivirira nzvimbo yepende kubva pakuoma nekukurumidza uye kudzivirira kukanda ganda, nokudaro kuvandudza kunaka kwepende.
4. Kumisa vamiririri uye stabilizers
Mumaindasitiri ekuputira uye pendi maumbirwo, HPMC inoshanda seyakanyanya kumisa mumiriri, kudzivirira pigment uye mafirita kubva pakugadzika. Nekuda kwekukora uye rheological gadziriso mhedzisiro yeHPMC, inogona kuita kuti sisitimu yekumisa igadzikane, ive nechokwadi chekuti pigment uye mafirita zvakagovaniswa mukupfeka, uye kuderedza delamination. Izvi zvinobvumira pendi kuchengetedza kufanana panguva yekuchengetedza uye kushandiswa, kudzivisa kusaenzana kwemavara kana kuchinja kwekuita kunokonzerwa nekugadzirisa pigment.
5. Kuvandudza kushanda kwekuvaka
Iko kukora, kunyorova, kuumba firimu uye zvimwe zvivakwa zveHPMC zvinogona kuvandudza mashandiro ekuvaka kwejasi kune imwe nhanho. Semuyenzaniso, lubricity yeHPMC inogona kuvandudza manzwiro kana uchikwesha nekukunguruka, zvichiita kuti pendi ive nyore kubata. Pamusoro pezvo, HPMC inokwanisa kudzora kumhanya kwekuomesa kwepende, izvo zvisingangogone kuderedza mavanga ependi asiwo kudzivirira matambudziko ekuvaka anokonzerwa nekunyanya kuomesa.
Yekupfapfaidza yekuputira maitiro, HPMC inogona kuderedza spatter uye kuwedzera coating kuwirirana nekugadzirisa viscosity uye fluidity yejasi. Kune roller coating uye brush coating, HPMC inogona kuwedzera kunamatira kwejasi, kudzivirira kunyura kubva pakudonha nekudonha, uye kugadzirisa kutsetseka kwejasi.
6. Kushandisa mune zvakatipoteredza friendly coatings
Nekuenderera mberi kwekuvandudzwa kwezvinodiwa zvekuchengetedza kwezvakatipoteredza, mvura-based coatings iri kuwedzera kushandiswa muminda yeindasitiri. HPMC i polymer inonyungudika mumvura, inonyanya kukodzera mabhanhire emvura uye pendi dzinoenderana nemamiriro ekunze. Mumvura-yakavakirwa machira, HPMC haingogone kuvandudza iko kukora kwejasi, asi zvakare kuparadzira zvakadzika mavara akasiyana-siyana uye ekuwedzera mumvura, kuderedza kuburitswa kweanoputika organic compounds (VOC), uye kutevedzera zvinodiwa nemirairo yezvakatipoteredza.
7. Anti-sag uye kuenzana zvivakwa
Munguva chaiyo yekupenda, kuramba kwependi kusag kwakakosha, kunyanya kana kupenda nzvimbo dzakamira. Nekugadzirisa viscosity yepende, HPMC inogona kuvandudza mashandiro ayo anti-sag uye kuderedza kubuda kwependi pafacade. Pamusoro pezvo, HPMC inogona zvakare kuvandudza magadzirirwo ependi, ichiita kuti pamusoro pefirimu rependi rive rakatsetseka uye risina mabrashi mamaki, kuwedzera aesthetics yejasi.
8. Kuvandudza kusamira kwemamiriro ekunze
Iko kushandiswa kweHPMC mumachira kunogona zvakare kuvandudza kupikisa kwemamiriro ekunze kwejasi. Mukupenda kwekunze, pendi inowanzokanganiswa nemamiriro ekunze akadai semhepo, zuva, mvura, etc. HPMC inogona kuvandudza kupikisa kweUV uye kurwisa kuchembera kwefirimu rekuvhara, kunonoka kupera, kuita hupfu uye kuputika kwefirimu rekuvhara, uye kuve nechokwadi. kuti kupfeka kunochengetedza kunaka kwayo uye kushanda kwenguva yakareba.
9. Inogadziriswa yekuomesa nekukurumidza
Zvinoenderana nezvinodiwa zvakasiyana zvekuvaka, kumhanya kwekuomesa kwejasi uye pendi inoda kudzorwa zvakakodzera. HPMC inogona kushandura nguva yekuomesa yejasi kuti ienderane neyakasiyana mamiriro ekuvaka nekugadzirisa dosage yayo uye formula. Kunonoka kuomesa kumhanyisa kunobatsira kuvandudza nguva yekugadzirisa panguva yekushandisa, nepo kuomesa nekukurumidza kwakakodzera kune inodiwa maindasitiri ekupenda nharaunda.
10. Kudhura-kubudirira uye nyore kushandisa
Sechinhu chinodhura-chinowedzera chekuwedzera, kushandiswa kweHPMC mumaindasitiri ejasi uye pendi haingogone kuvandudza zvakanyanya kuita kwekupfeka, asi zvakare ine yakanaka mutengo-inoshanda. HPMC inogona kuwana yakanakira thickening uye rheology gadziriso mhedzisiro ine yakaderera dosi, kuderedza kushandiswa kwezvimwe zvinodhura zvinhu. Pamusoro pezvo, HPMC ine kugarisana kwakanaka, iri nyore kuwedzera nekusanganisa mune akasiyana mafomula, iri nyore kushanda, uye inokodzera kugadzirwa kwakakura kwemaindasitiri.
HPMC inoshandiswa zvakanyanya uye zvinobudirira mumaindasitiri ekukoira uye pendi. Kuburikidza nekukora kwayo kwakasarudzika, kugadzira firimu, kunyorova, kumiswa, rheology control uye zvimwe zvivakwa, inovandudza zvakanyanya kuvaka, kuyera, kuramba kwemamiriro ekunze uye kuchengetedzwa kwezvakatipoteredza kwejasi. Nekukwira kwemvura-yakavakirwa zvakatipoteredza zvine hushamwari majasi, HPMC ichaita basa rakakosha mumusika wemangwana maindasitiri ekupfeka machira kuzadzisa izvo zviviri zvinodiwa zveindasitiri nekuchengetedzwa kwezvakatipoteredza.
