HydroxyPropyl methylcellose (HPMC) ndeye polymer compound inowanikwa nemakemikari kugadzirisa zvirimwa zvechisikigo. Iyo ine yakanaka mvura solubility, isiri-yehupfu, kusava nehanya uye yakanaka biocomputer. Naizvozvo, inoshandiswa zvakanyanya pakupenda, kuvaka, mishonga, chikafu uye imwe minda. Muindasitiri yePendi, HPMC inoita basa rakakosha sedhimoni, rinogona kuvandudza kuita, kugadzikana uye kugadzirisa tekinoroji yependi.
1. Basa reHPMC seye pendi thickener
HPMC inotamba zvinotevera mabasa seyekuenda mune pendi:
(1) wedzera vhiza ye pendi
HPMC inogona kutora mvura uye nekuzvimba mumvura-yakavakirwa mapepa anonyanya kubhururuka keteni keteni Kuwedzera kweViscosity kunovandudza zvivakwa zve rateological kwependi uye nekuwedzera kuunganidza pendi yependi. Kunyanya, HPMC inogona kuita kuti iburuke uye yekupuruzira pende ichinyima uye kudzivirira kunyanyisa kusekerera kana kudonha.
(2) kuvandudza zvivakwa zvetsiva zvejasi
Iko kushandiswa kweHPMC mumatangi kunogona kuvandudza zvakanyanya zvivakwa zvavo zvemo, kunyanya pakukwirira kwakanyanya uye kudzikira masheya mitezo, uye kunogona kuchengetedza viscosity uye kugadzikana. Izvi zvakakosha zvakanyanya pakugadziriswa kwejasi mumamiriro ezvinhu akasiyana siyana, kunyanya zvekuvaka kana uchirova munzvimbo dzakakura. Nekugadzirisa iyo surure uye surure yeHPMC, iyo Fliliity yeCoating inogona kutongwa, kuitira kuti hazvisi nyore kuyerera kwazvo panguva yekushandisa, uye inogona kuchengetedza zvinhu zvakakodzera zvekuvaka.
(3) Kuvandudza kupararira kwakatwasuka kwejasi
Iko kukonzeresa mhedzisiro yeHPMC mumakonzo hakusi kungowedzera zvevisiko, asi zvakare kugadzirisa kuunganidzwa kwejasi. Kupararira kwakatwasuka kunoreva kugona kwekutora kwekunyatso kugoverwa pamusoro peiyo subtrate mushure mekuputika pasina kukonzera mottled kana zvisina kufanana zviitiko. HPMC inowedzera kushushikana kwepasi uye inokatyamadza maitiro ekuyerera ekuchera, kuitira kuti maCoating anoumba yunifomu uye yakasimba yekuvhara firimu pamusoro peiyo substrate.
(4) inowedzera nguva yakavhurika yekubatira
Semunhu akasarudzika, Hpmc zvakare ane basa rekuwedzera nguva yekuvhurika yekuvhara. Nguva yakavhurika inoreva nguva yekuti kubikwa kunoramba kuchiramba chiitiko panguva yekunyorera. Kuwedzeredza nguva ino kunobatsira kudzivirira kuungana kubva pakuomesa nekukurumidza panguva yekutsvaira, iyo inotungamira kusingaenzaniswi kana mamakisi ebrashi. HPMC inovandudza huwandu hwekuvhara, uchibvumira kuunganidzwa kwemvura-kwakavakirwa kuchengetedza viscosity yakakodzera kwenguva yakareba, kuve nechokwadi chekubatanidza coating maitiro.
(5) Simbisa kugadzikana kwekuchengetwa
Mhedzisiro yakakora yeHPMC zvakare inobatsira kusimudzira kutarisisa kwekuvharidzira, kunyanya muchikamu chakasungirirwa mvura, zvinodzikisira, zvinodzivirira, uye kuwedzera nguva yekuchengetera yekuvhara. Nekugadzirisa iyo molecular uremu uye degree rekutsiva kweHPMC, kusimba kwekuchengetera kunogona kuongororwa kuti hazvizokanganise kana kufungidzira munguva refu yekuchengetedza.
2. Kushandiswa kweHPMC mumvura-yakavakirwa mvura
Zvinyorwa zvakavakirwa mvura zvakakurudzirwa zvakanyanya mumakore apfuura nekuda kwekudzivirirwa kwavo kwezvakatipoteredza, zvisiri zvezvemamiriro ekunze, uye kusvibiswa kwakaderera. Iko kushandiswa kweHPMC mumvura-yakavakirwa mvura yejasi inonyanya kukosha. Izvo hazvingoita sechiitiko, asi zvakare zvinotora basa rakakosha mune zvinotevera zvinhu:
(1) kuvandudza fluidity uye kushanda
Iyo fluidity yejasi-yakavakirwa mvura inowanzo kukanganiswa nezviri zvemvura uye zvemukati zvakasimba. HPMC inogona kugadzirisa rheology yemvura-yakavakirwa mvura kuti ichengete yakakwira viscosity pamatanho eshear, nokudaro anoona kuti kubatanidzwa kune kugona kwakanaka panguva yekuvhara. Mukuwedzera, HPMC inogona zvakare kurudzira iyo iyo iyo yekuvhara, ndiko kuti, iyo coating ine imwe viscosity mune yakatarwa mamiriro, asi inogona kukurumidza kuderedza visikopa panguva yekunyorera kufambidzana kuti ifambise kuyerera.
(2) kuvandudza kudzikisira kwemvura kwemvura-yakavakirwa mvura
HPMC mamorekuru ane hydrophic mapoka, ayo anogona kusimudzira kushamwaridzana kwemavara emvura-yakavakirwa mvura. Munguva yekuomesa kwekunyora, HPMC inogona kuderedza zvinobudirira dambudziko rekubatanidza kuputika kwakakonzerwa nekubuda kwemvura, nekudaro tichivandudza kupokana kwemvura uye kuderedza kwekucheka.
(3) Simbisa iyo transparcy uye gloss yekubatanidza
Nekuda kwekukwira kwayo Solubility, HPMC inogona kubatsira machira emvura inokonzerwa nemvura inochengetedza huwandu hwepamusoro uye gloss. Mune zvimwe zvinokosha zvinobatanidza zvikumbiro, zvakadai seVarnishes uye zviyero zvakajeka, kushandiswa kweHPMC kunogona kuchengetedza kujekesa kwekucheka uye kugadzirisa gloss yekukwenenzvera kwekupedzisira.
3. Kushandiswa kweHPMC mune zvemafuta-zvakavakirwa
Mune zvemafuta-zvakavakirwa zviyo, HPMC inonyanya kushandiswa seyekudzora uye rheology murongo. Kunyangwe HPMC pachayo inova mvura-inokonzeresa, iyo yakanaka yakanaka mhedzisiro mumakororo ezvemafuta ekushandiswa kuchiri kushandiswa zvakanyanya. Mumidziyo ine mafuta, HPMC inogona kunyatsogadzirisa zvisizvo zvependi, kuvandudza kushungurudzika uye nekuvandudza kugadzikana kwependi, kudzivirira sediment in the pigment, uye kuderedza kugadzikana kwependi.
4. Zvakanakira HPMC semhereke
Kuenzaniswa neTizili Slickeds, kushandiswa kweHPMC mumapendi mune zvinotevera zvakakosha zvakanakira:
Dziviriro Yakanaka Yezvakatipoteredza: HPMC ndeyekubva kune inobva yakasikwa cellulose Cellulose uye haina zvinhu zvinokuvadza, saka zvakachengeteka kushandisa mumapendi uye haisvibise nharaunda.
STOUL SOLUBULILILLOLICE: HPMC ine yakanaka solubility uye kugadzikana mumvura-yakavakirwa mapepa emvura, inogona kupa yakakora mhedzisiro, uye haizokanganisa zvimwe zvivakwa zvependi.
Kuita kwakanakisa kwekuvaka: HPMC kunogona kunatsiridza zvinobudirira kuita kwependi, dzivisa kusati kwatanga kuomesa uye kusagadzikana kwekucheka, uye kwakakodzera kune dzakasiyana siyana coating progresiti.
Kuvandudza Kuchengetedzeka Kugadzikana: HPMC inogona kudzikisira zvivakwa zvemuviri uye zvemakemikari zvekupenda uye kuderedza iyo yakakundwa phenomenon iyo inogona kuitika panguva yekuchengetedza.
Sechirongwa chekombi, HPMC haigone kungowedzera zvevisiko zve pendi uye nekuvandudza rheology, asi zvakare kusimudzira kugadzikana, kuita kwekushanda uye kwekuvaka pendi. Iyo inoshandiswa zvakanyanya mumvura-yakavakirwa mvura pendi uye nemafuta-akavakirwa pendi. Nekugadzirisa chimiro chayo cheMorecular uye kusunganidzwa, kuita kwekuchinjisa kunogona kugadziriswa kuti usangane zvinodiwa zvekugadzira kwemhando dzakasiyana dzezvemhando dzakasiyana dzemhando dzakasiyana dzemhando dzakasiyana dzemhando dzakasiyana dzemhando dzakasiyana dzemhando dzakasiyana dzemhando dzakasiyana dzemhando dzakasiyana dzezvemhando dzakasiyana dzemhando dzakasiyana dzemhando dzakasiyana dzemhando dzakasiyana dzemhando dzakasiyana dzemhando dzakasiyana dzemhando dzakasiyana dzemhando dzakasiyana dzemhando dzakasiyana dzemhando dzakasiyana dzemhando dzakasiyana dzemhando dzakasiyana dzezvemhando dzakasiyana dzemhando dzakasiyana dzemhando dzakasiyana dzemhando dzakasiyana dzemhando dzakasiyana dzemhando dzakasiyana dzemhando dzakasiyana dzezvemhando dzakasiyana dzemhando dzakasiyana dzemhando dzakasiyana dzemhando dzakasiyana dzemhando dzakasiyana dzematanho ezvipfuyo zvakasiyana zvejasi. Nekuwedzera kwekuda kwekushamwaridzana kwehukama uye tarisiro yekunyora, tarisiro yekushandisa yeHPMC ichave yakawedzera uye ichava imwe yekiyi inoshanda yekuwedzera muCogings indasitiri.
