Hydroxyprupyl methylcellose (HPMC), Seimwe chinhu chakakosha chekuvaka chinowedzera, chinoshandiswa zvakanyanya muzvipfuyo zveporcelain, kunyanya mune formula yeyakaomeswa poda. Izvo hazvingangove kungogadzirisa basa rekuvaka rekuvhara, asi zvakare kuvandudza kudzikisira kwemvura, kuderedza uye kuiswa kwekucheka.
1. Zvivakwa zve hydroxyprupyl methylcellose
Hydroxyprusyl methylcellose inzvimbo yekunyoreswa yemvura yakagadziridzwa kubva kune yakasikwa chirimwa cellulose. Maitiro ayo makuru anosanganisira:
Kukakavara:Kimicell®hpmc inogona kuwedzera zvakanyanya zvevhiza yekuvhara, vachiita kuti coating yakawanda yakagadzikana panguva yekuvaka.
Solubility yemvura:Iyo ine yakanaka mvura solubility uye inogona kuumba mhinduro yakagadzikana mumvura.
Firimu-kugadzira pfuma:Inogona kuumba yunifomu yemagetsi uye ichivandudza kuseka kwemusoro uye kufanana kwekuvhara.
Adhishing:Kuvandudza kuderedza kwekuvhara kune base pamusoro (senge simende, masonry, huni, etc.).
Kuvandudza Kushanda Kwekuchera:Inogona kugadzirisa iyo fluidity uye kuchengetwa kwemvura kweiyo yakaoma poda inokwira, inowedzera nguva yekuvakwa, uye dzivisa kusagadzikana kwekusagadzikana.
2. Basa re hydroxypropyl methylcellose mune yakaoma poda poda porcelain-like pendi
Mune yakaoma poda porcelain-kunge pendi, hpmc inonyanya kutamba mabasa anotevera:
Kukora uye kugadzirisa viscosity:Iko kukonzeresa mhedzisiro yeHPMC kunoita kuti pendi ive yakanaka rheology panguva yekugadzirira uye kushandiswa, uye hazvisi nyore kuburitsa sagging.
Kuvandudza Kuita Kwekuvaka:Nekugadzirisa kusimba uye mvura inobata mukana wependi, HPMC inogona kuvandudza kuyaridzwa panguva yekuvaka, kunyanya mune yakanyanya tembiricha kana kuoma nguva, kuita kuti pendi iri nyore kushandisa uye kutema.
Kuvandudza Dhiziri:HPMC inogona kuwedzera kudenha pakati pependi uye substrate, kunyanya pane simende subtrate kana masonry substrates, inopa kusimba kusimba uye kuderedza chiitiko chekuputira pendi.
Kudzivirira Sevemention uye kuoma:HPMC ine yakanaka yekumiswa zvinhu, iyo inogona kudzivisa kunyatso kudzivirira iyo svina yeiyo yakaoma poda pendi panguva yekuchengetedza uye ive nechokwadi chekufanana kwependi.
Kuvandudza kudzivisa kwemvura uye kupenga kuramba:HPMC inogona kuvandudza kudzivisa kwemvura yekubatira, kuwedzera kupaza kudzikisira kwekuvhara, uye kuita kuti coating yakawanda kana yakanyorova kana nharaunda yekunze inoshanduka zvakanyanya.
3.
Dry Powder kutevedzera porcelain plint kazhinji ine zvinotevera zvinhu zvikuru:
Inorganic filers:akadai talcum poda, anorema calcium poda, etc. aya mafirita anoshandiswa kugadzirisa iwo maitiro uye kuomarara kwependi uye kubatsira kuunganidza kuti awane mukana wakanaka.
Resin kana emulsion:Inowanzo shandiswa resins inosanganisira acrylic resin, polyurethane resin, etc., iyo inogona kusimudzira iyo kuderedza, kuomarara uye kudzikisira kwependi.
Modified cellulose:Yakadai seHPMC, iyo huru inoshanda yerudzi urwu rwechinhu ndeyekugadzirisa viscosity, fluidity, kuiswa uye kugadzikana kwependi.
Colant:senge pigment, yaishandiswa kugadzirisa ruvara rwependi, vanhu vanozivikanwa ndere titanium dioxide, kabhoni dema, nezvimwe.
Chengetedza:yaishandiswa kudzivirira kukura kwehutachiona kwehutachiona mupendi uye uve nechokwadi chekuti hupenyu hwebasa hwependi.
Plasticzezer uye kufambisa mumiririri:yaishandiswa kuvandudza kushoma kwemusoro wekukanda uye kudzivisa kusarongeka kwemukati pane inobatanidza.
4. Iyo huwandu uye huwandu hweHPMC mune yakaoma poda kutevedzera porcelain pendi
Mune yakaoma poda kutevedzera porcelain pendi, huwandu hweHPMC yakawedzerwa kazhinji maakaunti kweanenge 0.5% -2% yeiyo yese pendi pendi formula. Iyo chaiyo ratio inoenderana nezvinodiwa coating performance. Izvi zvinotevera fomula chaiyo (kutora gumi kg yakaoma poda ichivharira semuenzaniso):
Inorganic filler (talcum poda, inorema calcium poda, nezvimwewo):dzinenge 6-7 kg
Resin:About 1.5-2 kg
Hydroxyprusyl methylcellose (HPMC):Inenge 0.05-0,2 kg
Pigment (senge titanium dioxide):Inenge 0.5-1 kg
Chengetedza:Inenge 0.05 kg
Plasticzezer uye kufambisa mumiririri:dzinenge 0.1 kg
Kugadziriswa kwakananga kwefomula kunofanirwa kutsanangurwa maererano nezvinodiwa zvekuvaka uye zvinodiwa pakuita, kunyanya mumamiriro ekunze ematunhu akasiyana, huwandu hweHPMC dzinoshandiswa kuti rive rakagadzirirwa.
5. Kushandiswa uye Zvinotarisirwa
Paunenge uchishandisa HPMC, inokurudzirwa kutevera matanho anotevera:
Pre-kunyorovesa isati yasangana: Kimicell®hpmc Poda inofanira kusanganiswa nemvura isati yawedzera zvimwe zvigadzirwa, kuti zvive zvanyatsowedzera mvura, kuitira kuti udzivise hpmc agglomeration.
Towerse:Paunenge uchisanganisa imwe yakaoma poda gadziriso,Hpcinofanirwa kuwedzerwa zvishoma nezvishoma kuti udzivise kusakwana kusakwana nekuda kwekuwedzera kwakanyanya.
Zvakanyanyisa kusanganiswa:Mufomula, zvese zvinongedzo zvinoda kunyorwa zvakanyorwa kuti uve nechokwadi chekuti HPMC inogona kuita zvizere basa rayo mukucheka.
Mamiriro ekuchengetedza:Dry poda kutevedzera porcelain coatings inofanira kuchengetwa munzvimbo yakaoma uye inotonhorera kuti udzivise tembiricha yakanyanya uye humidity inokanganisa kunaka kweiyo coating.
Iko kushandiswa kwehydroxyprishpropyl methylcellose mune yakaoma poda kutevedzera porcelain kosi inogona kuvandudza kuita kwekuvaka, kuderedza kwemvura yekubatira, vachiita kuti kuunganidzwe zvakanyanya uye kusimba. Kuburikidza nekururamisa Fomu Dhizaini uye Shandisa nzira, zvakanakira HPMC zvinogona kuzoshandiswa zvizere, kuita kwakazara kwekubatanidza kunogona kuvandudzwa, uye zviitiko zvakasiyana zvinodikanwa zvinogona kusangana. Muzvikumbiro chaicho, huwandu hweHPMC yakawedzerwa hunoda kugadziridzwa zvinoenderana nemamiriro ezvinhu chaiwo kuti ave nechokwadi chekuti kuunganidza kunowana mhedzisiro yaunoda.
