Chikumbiro tekinoroji yeHydroxyTHLYL methylcellose muCoatings

Nhanganyaya
HydroxytHyl methylcellose (Hemc) is cellulose inobviswa zvakanyanya kushandiswa mune dzakasiyana siyana maindasitiri ekushandisa, kunyanya mumakonzo. Senge isiri-ionic cellulose ether, hemc inozivikanwa neyakaomesesa firimu-kugadzira, kudzokorora kwemvura, uye kuzvidzora, kuita kuti ive yakakosha mukuumbwa kwejasi.

Zvivakwa zve hemc

Hemc iri synthesised neiyo cellulose ine ethylene oxide uye methyl chloride, inokonzeresa mune polymer ine hydroxyteth uye mapoka emhando. Uku kugadziridzwa kunopa zvivakwa zvakasarudzika kune hemc, kusanganisira:

Solub Solubility: Hemc inodonha zviri nyore mumvura inotonhora, kugadzira yakajeka uye viscous mhinduro.
Akakora Agent: Inopa yakakosha viscossity, kuvandudza zvivakwa zvezvinyorwa zvejasi.
Film formation: hemc inogadzira inoshanduka uye mafirimu akasimba, ayo anobatsira mukugadzika kwejasi.
Kuchengeta kwemvura: Iyo ine mvura yakakwirira yekuchengetwa, iyo yakakosha kurapa kwakaringana nekuoma kwejasi.
PH Simba: Hemc mhinduro yakagadzikana pamusoro peiyo ples ph range, ichiita kuti ive yakakodzera kune dzakasiyana siyana mafambiro.

Michina yechiitiko muCoatings

Hemc anoita kunyanya seanoti, STabilizer, uye nemvura-inochengetedza mumiririri mukubatanidza mafomu.
Maitiro anobva kune iyo hemc mabasa anosanganisira:
Kuwedzera uye rheology shanduko: nekuwedzera iyo visikoka yemusanganiswa wekubatanidza, hemc inovandudza zvivakwa zvayo zvekushandisa, sekushungurudza uye kuyerera. Iyo polymer maketani e hemc entangle uye gadzira chimiro chetivhi chinowedzera huwandu hwekusvitswa kweiyo fomu.
STabilization: Hemc inobatsira kusimudzira kuparadzaniswa kweiyo pigment uye zvimwe zvimedu zvevakabatanidza mukubatanidza, kudzivirira sosi uye kuona yunifomu yeruvara uye kuumbwa.
Kudzokorora kwemvura: Munguva yekuomesa, hemc inochengetedza mvura mukati meiyo firimu yekuvhara, kudzivirira kusati kwatanga kuoma uye kuverengera kugadzirwa kwemafirimu. Izvi zvinonyanya kukosha mumvura-yakavakirwa mvura yejasi, uko manejimendi anonyanyisa kutsoropodza.
Firimu kugadzirwa: Paunenge uchiomesa, hemc inoumba firimu rinoenderera uye rinochinja-famba rinowedzera midziyo yemuchina uye kujaira kwekuvhara.

Zvakanakira MuCoating Zvikumbiro

Kubatanidzwa kweHemc mumakonzo kunopa zvinobatsira akati wandei:

Yakavandudzwa Mashandiro Ekushandisa: Yakavandudzwa Viscosity uye Rheology inobvumira kuti ishandiswe applicet, kuderedza maruva emakwenzi uye roller straks.
Yakavandudzwa Workability: Iyo yakawedzera nguva yakavhurika yakapihwa neHemc inobvumidza zviri nani kuwanda uye kuyerera, zvichikonzera kuyamwa kakawanda.
Durability uye kuchinjika: Mafirimu akaumbwa neHEMC anochinja uye anodzivirira kupaza, achiwedzera hupenyu hurefu hwekuvhara.
Mutengo-Kubudirira: Hemc jaya rinodhura rinogona kugadzirisa zvakanyanya kuita kwejasi risina basa rakawanda rekuumbwa.
Eco-Hushamwari: Kuve unobva kune yakasarudzika cellulose, hemc inowedzera kushamwaridzana uye biodegradle ..

HydroxytHyl methylcellose indasitiri inoverengeka uye inokosha yejasia indasitiri, ichipa mhando dzezvakanaka kubva mukuvandudzwa kwekushandisa kuti uwedzere kusimba uye mutengo-kushanda. Yayo yakasanganiswa yekusanganisa, inosimbisa, kudzikamisa mvura, uye mafirimu ekuumba midziyo inoita kuti ive yakakosha mumamiriro akasiyana siyana ekubatanidza. Nekudaro, chikumbiro chayo chinoda kunyatsofungisisa nezvekusangana, kuenderana, kupaza, tembiricha, uye pH kuzadzisa kuita kwakakwana. Sezvo maCoatings indasitiri inoenderera mberi kusimuka, hemc icharamba iri chinhu chakakosha mukuvandudzwa kwekusimudzira-kwecoinings.
