Methyl hydroxyethyl cellulose (MHEC) inokosha cellulose ether compound ine dual modifications ye methylation uye hydroxyethylation.Mumvura-based coatings, MHEC inoita basa rinokosha neyakasiyana-siyana yemuviri uye makemikari zvinhu.
I. Maitiro ekuita
Kukora
Iwo hydroxyethyl uye methyl mapoka muMHEC molecular chimiro anogona kuumba network dhizaini mune aqueous mhinduro, nokudaro zvinobudirira kuwedzera viscosity yekupfeka.Uku kukora mhedzisiro kunoita kuti ikwanise kuwana yakanakira rheology pane yakaderera concentration, nekudaro ichidzikisa huwandu hwekuputira uye kuchengetedza mari.
Rheological kugadzirisa
MHEC inogona kupa iyo yekupfeka yakanakisa fluidity uye anti-sagging zvivakwa.Yayo pseudoplastic maitiro anoita kuti iyo coating iite yakakwira viscosity munzvimbo yakamira, uye viscosity inogona kuderedzwa panguva yekushandisa, iyo iri nyore kubhurashi, roller coating kana kupfapfaidza mashandiro, uye pakupedzisira inogona kukurumidza kudzoreredza iyo yekutanga viscosity mushure mekuvakwa kwaitwa. kupera, kuderedza sag kana kudonha.
Kuchengetedza mvura
MHEC ine yakanaka yekuchengetedza mvura uye inogona kunyatso kudzora kuburitswa kwemvura.Iyi pfuma inonyanya kukosha pakudzivirira mvura-based peints kubva pakuputika, powdering uye zvimwe zvikanganiso panguva yekuomesa, uye inogonawo kuvandudza kutsetseka uye kufanana kwekuputira panguva yekuvaka.
Emulsion kugadzikana
Sezvinoita surfactant, MHEC inogona kuderedza tension yepasi ye pigment particles mumvura-based peints uye kukurudzira kupararira kwavo kweunifomu muzvinyorwa zvepasi, nokudaro kuvandudza kugadzikana uye kuenzana kwepende uye kudzivisa kuyerera uye kunaya kwepigment.
Biodegradability
MHEC inotorwa kubva kune yakasikwa cellulose uye ine biodegradability yakanaka, iyo inoita kuti ive nemabhenefiti ari pachena mumapendi ane ushamwari emvura uye inobatsira kuderedza kusvibiswa kune zvakatipoteredza.
2. Mabasa makuru
Thickener
MHEC inonyanya kushandiswa seyakakora yependi yemvura kuti ivandudze mashandiro ayo ekuvaka uye mhando yefirimu nekuwedzera viscosity yepende.Semuenzaniso, kuwedzera MHEC kune latex pendi inogona kuumba yunifomu yekuputira pamadziro kudzivirira pendi kubva pakudonha uye kudonha.
Rheology regulator
MHEC inogona kugadzirisa rheology yemvura-based paints kuti ione kuti iri nyore kushandisa panguva yekuvaka uye inogona kukurumidza kudzokera kune yakagadzikana.Kuburikidza neiyi rheological control, MHEC inonyatso kuvandudza mashandiro ekuvaka kwejasi, ichiita kuti ive yakakodzera kune akasiyana maitiro ekupfeka.
Mushandi wekuchengetedza mvura
Mumvura-yakadzika midzi, mvura inochengetedza pfuma yeMHEC inobatsira kuwedzera nguva yekugara kwemvura mumucheka, kunatsiridza kuomeswa kwehuputi, uye kudzivirira kuberekwa kwekuputika uye kukanganisa kwepamusoro.
Stabilizer
Nekuda kwekugona kwayo emulsifying yakanaka, MHEC inogona kubatsira mvura-yakavakirwa majasi kuumba yakagadzikana emulsion system, kudzivirira kunaya uye flocculation ye pigment particles, uye kuvandudza kugadzikana kwekuchengetedza kwekuvhara.
Mafirimu-kugadzira rubatsiro
Munguva yekugadzira firimu yekugadzira, kuvapo kweMHEC kunogona kukurudzira kufanana uye kutsetseka kwechifukidzo, kuitira kuti kuvhara kwekupedzisira kuve nekuonekwa kwakanaka uye kushanda.
3. Mienzaniso yekushandisa
Latex pendi
Mune latex pendi, basa guru reMHEC riri kuwedzera uye kuchengetedza mvura.Inogona kuvandudza zvakanyanya kubhurashi uye kutenderedza zvimiro zvependi yelatex, uye ive nechokwadi chekuti iyo coating inochengetedza kunaka kwakanaka uye kufanana panguva yekuomesa.Uye zvakare, MHEC inogona zvakare kukwidziridza anti-splash uye sagging zvivakwa zve latex pendi, zvichiita kuti basa rekuvaka riite mushe.
Pendi yehuni yemvura
Mumvura yependi yehuni, MHEC inovandudza kutsetseka uye kufanana kwefirimu yepende nekugadzirisa viscosity uye rheology yepende.Inogonawo kudzivirira pende kubva pakuumba sagging uye kusvibisa pamusoro pehuni, uye kuwedzera kushongedza uye kusimba kwefirimu.
Mvura yekugadzira pendi
Kushandiswa kweMHEC mumvura yependi yekuvaka kunogona kuvandudza mashandiro ekuvaka uye kupfekedza kunaka kwepende, kunyanya kana yekuputira nzvimbo senge madziro uye sirin'i, inogona kunyatso kudzivirira kudonha uye kudonha kwepende.Mukuwedzera, nzvimbo yekuchengetedza mvura yeMHEC inogonawo kuwedzera nguva yekuoma kwepende, kuderedza kuputika uye kukanganisa kwepamusoro.
Pendi yeindasitiri yemvura
Mumvura yependi yemaindasitiri, MHEC haingoite seyakakora uye kuchengetedza mvura, asiwo inovandudza kupararira uye kugadzikana kwepende, kuitira kuti pende inogona kuchengetedza kuita kwakanaka uye kusimba munzvimbo dzakaoma dzeindasitiri.
IV.Market tarisiro
Nekuwedzera kuomarara kwemitemo yekuchengetedza kwezvakatipoteredza uye kuwedzera kuri kuda kwezvinhu zvakasvibirira zvekuvakisa, kudiwa kwemusika kwependi dzinowanikwa nemvura kuri kuramba kuchikura.Sekuwedzera kwakakosha mumapendi emvura, MHEC ine tarisiro yakakura yemusika.
Kusimudzirwa kwemutemo wezvakatipoteredza
Pasi rose, mitemo yezvakatipoteredza yakawedzera kuomesa zvirambidzo pakubuda kwevolatile organic compound (VOC), izvo zvakasimudzira kushandiswa kwemachira emvura.Sekuwedzera kwezvakatipoteredza, MHEC inoita basa rakakosha mumachira emvura, uye kudiwa kwayo kuchawedzera nekuwedzera kwemusika wemvura.
Kukura kudiwa muindasitiri yekuvaka
Kuwedzera kudiwa kweyakaderera-VOC, yakakwirira-yekuita machira muindasitiri yekuvaka yakasimudzirawo kushandiswa kweMHEC mumabhati ekuvaka emvura.Kunyanya kwemukati nekunze kwemadziro emadziro, MHEC inogona kupa yakanakisa kuvaka kuita uye kusimba kuzadzisa kudiwa kwemusika.
Kuwedzera kushandiswa kwemaindustry coatings
Kukura kuri kudiwa kwemachira ane hushamwari munharaunda yeindasitiri kwakasimudzirawo kushandiswa kweMHEC mumachira emvura maindasitiri.Sezvo maindasitiri ekuputira achikura akananga kune hushamwari uye nepamusoro-kuita mafambiro, MHEC ichaita basa rakakosha mukuvandudza mashandiro ekuputira uye hunhu hwezvakatipoteredza.
Methyl hydroxyethyl cellulose (MHEC) inobata basa rakakosha mukuputira mumvura nekukora kwayo kwakanakisa, rheology kugadzirisa, kuchengetedza mvura, emulsion kugadzikana uye biodegradability.Kushandiswa kwaro mumvura-based coatings hakungogadziri kushanda kwekuvaka uye kupfekedza kunaka kwehuputi, asiwo kunopindirana nemaitiro ekuchengetedzwa kwezvakatipoteredza uye kusimudzira kwakasimba.Nekuwedzera kuri kuita musika kudiwa kwepamusoro-kuita, yakaderera-VOC mvura-yakavakirwa machira, tarisiro yekushandiswa kweMHEC mundima iyi ichave yakakura.
