Application yehydroxyethyl cellulose (hec) mune yejasi indasitiri

1. Sumo

Hydroxethyl Cellulose (Hec) is nonitic cellulose ether yakawanikwa nekuita yakasikwa cellulose neEtralene oxide mushure mekurapwa kweAlkali. Hec yakave ichishandiswa zvakanyanya mumachira endyoko nekuda kweiyo yakasarudzika yemuviri uye yemakemikari zvinhu, yakadai solubility yemvura, yakanaka viscosity yekugadzirisa kugona uye mamiriro ekugadzirisa.

2. Basic hunhu hwehimwe hec

Hec ine zvinotevera zvakakosha maitiro, zvichiita kuti ive yakakosha muCoatings Indasitiri:
Solub mvura: Hec inogona kunyungudutswa mumvura inotonhora kuti aumbe yakajeka kana microemulsion solution, iyo inogonesa kunyatsogadzirisa zvisizvo zvekuvhara.
Kuita kwakasimba: Hec ine yakanakisa kurongedza zvinhu uye inogona kuwedzera zvakanyanya zvivakwa zvemhinduro pane yakaderera nzvimbo, nekukasira kugadzirisa uye mafirimu ekubatanidza.
Kumiswa kuumbwa: Hec kunogona kudzikisira kumiswa uye kudzivirira iyo singivation yemifananidzo kana mafirita mukubatanidza, nokudaro achivandudza kufanana uye kugadzikana kwekuchengetwa.
Thiskotropy: Hec inopa iyo yekubatanidza system yakanaka, iri, iri pasi pechiitiko chesimba reShear, iyo yekuvhara inoderedza, iyo yakakodzera kuvaka; Kana iyo Simba reShear rakasunungurwa, iyo coating inokurumidza kudzoreredza vhiza yayo yekutanga, kuderedza kusekerera nekupararira.
Kudzivirira Coliid Evha: HEC inogona kuumba mhandemo yekudzivirira kudzivirira kuhurika kwePolyx Polymers uye kuvandudza kugadzikana kwekucheka.

3. Kunyatsoitwa kwehwanda mujasi

3.1 Latex Pendi

Iko kushandiswa kwehisheni muLatex pendi inonyanya kuratidzwa mune thizi, stabilizers uye mvura yadzinza:

Thickener: Hec inogona kuwedzera zvakanyanya kuvenga kweLatex pendi, nokudaro ichivandudza iyo fluidity nekuvakwa kwependi. Nekugadzirisa kusungwa kwehwanda, iyo yakakodzera viscosity inodiwa kune nzira dzakasiyana dzekuvaka (dzakadai sehutsinye, ichirovera, uye kupfira) kunogona kuwanikwa.
Stabilizer: Hec inogona kudzivirira kunyatsoita kuti sedimentation yemifananidzo uye mafirita mune latex pendi, uye kuvandudza kufanana uye kugadzikana kwekuchengetedza kwependi.
Mvura inochengetedza mvura: Hec ine yakanaka yekuchenjera. Munguva yekuvaka, inogona kudzivirira iyo mvura pendi kubva pakuvaputira nekukurumidza, nekudaro ichidzivirira kupaza uye nekuvandudza iyo firimu pendi uye kusimba kwefirimu rependi.

3.2 Mvura-yakavakirwa Wood Pendi

Mune mvura-yakavakirwa mvura pendi, hec inonyanya kushandiswa seyakaomerera mumiririri uye SAG Control Mumiriri:

Mazinga Agent: HEC inopa mvura-yakavakirwa mapendeketi ehuni

Sag Control: Nekuvandudza iyo thision yemvura-yakavakirwa mapenderi, hec inogona kunyatso kudzora SAG yePendi kana yaiswa pamusoro pekuvandudza, kugadzirisa maitiro ekuvaka uye pendi yemhando yefirimu.

3.3 Architectural Coatings

Muzvakanyorwa zvezvivakwa (zvakadai seyamadziro emadziro emadziro uye madziro emadziro emadziro), hec inoita basa rakakosha seyakagwinya, kuparadzira uye kugadzirwa firimu kubatsira:

Thickener: Hec inowedzera iyo yekuzvidza kosi yekuvaka, ichiita kuti ive neakanaka zvekuvaka panguva yekuvaka, kuderedza sag nekudonha, uye kuona gobvu uye kufanana kwekuvhara.
Kuparadzira: Hec kunogona kupararira uye kusimbisa pigment zvimedu, kudzivirira kubva pakuwedzera uye kugadzirisa, uye kugadzirisa kuparadzaniswa uye kufanana kwekuvhara.
Firimu-Inobatsira Rubatsiro: Hec inogona kuvandudza iyo firimu-inoumba zvivakwa zvekuchera, kusimudzira kuumbwa uye kuomesa mechanices uye kujaira yefirimu pendi.

3.4 Zvikuru zvejasi

Mune zvimwe zviyero zvakakosha (zvakadai seanoridza-corrosion zvipfuyo, kudzoreredza kwemoto, uye hec inowedzera kukosha kwekuita kuburikidza nekubatanidza kuburikidza nekuita kwayo, uye rheology kudzora mabasa:

Anti-Corrostion Coatings: Hec inovandudza mavhiza uye kumiswa kugadzikana kwejasi-corroson marara, izvo zvinobatsira kutojira uye kuumba dense yekudzivirira.
Zvipoto zvinodzoreredza zvidzitiro: Iyo yepamusoro-firimu yekuumba midziyo yehec inobatsira machira anodzora moto gadzira tembiricha yakakwirira uye ichivandudza kudzikisira moto wekutakura.
Mafuta emisimboti ezvipenga

4. Hec kusarudzwa uye shandisa matanho ekudzivirira

Paunenge uchisarudza uye uchishandisa hec, iyo inotevera pfungwa inofanira kucherechedzwa:

Viscosity kusarudzwa: Sarudza yakakodzera hecus viscosity giredhi maererano nemasisitimu akasiyana ekubatanidza. Semuenzaniso, yakakwirira-viscosity hec yakakodzera kuunganidza masisitimu ane huwandu hwezvemukati kana yakakwira viscosity, nepo low-viscosity hec yakakodzera masisitimu ane yakaderera yakasimba zvemukati kana yakaderera viscosity.
Kuwedzera nzira: Kuti udzivise kuumbwa kwemapundu kana hec yakanyungudutswa mumvura, nzira yekuwedzera zvishoma nezvishoma inowanzoitwa, uye tembiricha yakawedzerwa nenzira kwayo uye nguva yekukurudzira inowedzerwa panguva yekunyungudika.
Kuenderana: apo hecc inoenderana nezvimwe zvinowedzera (sekuvaparadzira uye vanozvivharidzira), kutarisirwa kunofanirwa kubhadharwa pakutaurirana kwavo kuti vadzivise kuwirirana.

5. Renguva yemberi rekusimudzira maitiro

Nekukura kwekuenderera kweiyo indasitiri inovhara, izvo zvinodiwa nekubatanidza mashandiro ari kuwedzera zuva nezuva. Semunhu anokosha anoshanda, hec ane tarisiro huru yekushandisa. Mune ramangwana, kushandiswa kwehec mumakonzo kunogona kukura munzira dzinotevera:

Green uye Yakatipoteredza Dziviriro: Gadzira yakaderera-VOC, Solvent-yemahara zvigadzirwa zveHoc kuti uwane zvinodiwa zvedziviriro uye zvinodikanwa zvemusika.
Inoshanda Kugadziridzwa: Kuburikidza nemakemikari kugadziridzwa kana kugadziridzwa kwemuviri, hec inopihwa matsva ekuita zvinhu, senge antibacterial fungidziro, faniffuling, kuzvishingisa, nezvimwe.
Zvigadzirwa zvakakwirira-kuita: Gadzira zvigadzirwa zvehec zvakakodzera kuti zvibodzwa zvepamusoro-soro kuti usangane nezvinodiwa zvezvakakwirira zvezvekutengesa zvakakwirira mumunda wekuvaka, motokari, zvikepe, nezvimwewo.
HydroxytHyl Cellulose (Hec), seyakawedzera chiitiko, inoita basa rakakosha muCogings indasitiri. Yakanakisa kuremerwa, kumiswa, iyo thishidropic uye yekudzivirira colloid mhedzisiro inoshandiswa zvakanyanya mumatanho ekurapa Nekukura kuri kuramba kuchiramba kwejatings indasitiri, tarisiro yekushandisa yehec ichave yakawedzera. Mune ramangwana, nekuvandudza maitiro ekutsigira uye maitiro anoshanda ehec, kukosha kwayo kwekunyorera mumakonzo kuchadzikiswa.
