Ndedzipi zvinonyorwa zve cellulose ether muminda dzakasiyana?

Cellulose etheris is is-ionic semi-synthetic yakakwira molecular polymer, iyo iri manyorerwo-nyoro uye solvent-soluble. Iyo ine mhedzisiro dzakasiyana mumaindasitiri akasiyana. Semuenzaniso, mune zvemakemikari zvekuvaka, ine zvinotevera zvinotevera mhedzisiro:

① mvura inochengetedza mumiririri, ②tickerer, ③Lelviling pfuma, ④Film inoumba pfuma,

⑤binder

MuPolyvinyl chloride indasitiri, iri elsifier uye inopararira; Muindasitiri yechechi, iyo inosungirwa uye inononoka uye inodzorwa inosunungura zvinhu, etc. nekuti cellucose ine akasiyana siyana emhedzisiro, munda wacho munda zvakare wakanyanya kuwanda. Tevere, ini ndichatarisa pakushandiswa uye kushanda kwe cellulose ether mune dzakasiyana siyana zvekuvaka.

In latex pendi

Muindasitiri yeLatex Paint, kusarudza hydroxytHyl cellever Basa guru reHydroxyTH muLatex Pendi iri kuunganidza pombi, batsirai kuparadzaniswa kweiyo pigment, uye kuwedzera iyo visikopo yezvinhu, izvo zvinobatsira pakubata kwekuita kwekuvaka : HydroxytHyl cellulose inonyanya nyore kushandisa. Inogona kunyungudutswa mumvura inotonhora kana mvura inopisa, uye haina kukanganiswa neiyo ph kukosha. Inogona kushandiswa zvakachengeteka pakati pePi kukosha 2 ne12. Nzira dzekushandisa dzinotevera:

1. Wedzera zvakananga mukugadzira

Iyi nzira, hydroxytHyl cellyl merydy mhando inofanira kusarudzwa, uye iyo hydroxyll cellulose ine nguva yekunyungudika yemaminitsi anopfuura makumi matatu inoshandiswa. Matanho ari Sechinotevera: Zvese zvekunyepedzera zvakanyudzwa

2.

Iyi nzira inogona kusarudza Instant mhando, uye ine anti-nyoro-nyoro mhedzisiro cellulose. Iko mukana wenzira iyi ndeyekuti ine yakakura yekuchinjika uye inogona kuwedzerwa zvakananga kune latex pendi. Nzira yekugadzirira yakafanana nematanho ①-④.

3. Ita iyo muPorridge yezosvika pakushandisa

Sezvo organic sol sol sol murombo sol sol soles (insoluble) ye hydroxythethyl, aya molies anogona kushandiswa kuumba porridge. Iyo inowanzo shandiswa organic solics zvinwiwa zveganda muLatex Pendi mafomu, akadai seEthylene Glycol. Iyo porridge hydroxytHyl cellulose inogona kuwedzerwa zvakananga kune iyo pendi. Ramba uchimutsa kusvikira yakanyungudutswa.

In putty

Parizvino, mumaguta makawanda munyika yangu, iyo inodzivirira mvura uye ine hushamwari-kushamwaridzana Iyo inogadzirwa neacetal yakaitwa yeVinyl doro uye formaldehyde. Naizvozvo, izvi zvinyorwa zvinobviswa zvishoma nezvishoma nevanhu, uye cellulose ether zvigadzirwa zvevashandi zvinoshandiswa kutsiva izvi zvinyorwa. Ndokureva kuti, kuti ubudirire kwekuzvidzivirira kwezvakatipoteredza zvekuvaka, cellulose ikozvino ikozvino ndiyo chete zvinyorwa.

Mukutadza kwemvura-inodzivirira, yakakamurwa kuva marudzi maviri: yakaoma poda putty uye putty paste. Pakati pemhando mbiri idzi dzekutyisa, methyl cellulose uye hydroxypruppropyl methyl inofanira kusarudzwa. Iyo viscosity spection inowanzoitika pakati pe40000-75000CPS. Mabasa makuru e cellulose ari kuchengetwa kwemvura, kusungwa uye kuumbwa.

Sezvo iyo Putty Formelas yevanogadzira zvakasiyana, mamwe egrey calcium, chiedza calcium, chena calcum poda, etc. nemafomu maviri zvakare akasiyanawo. Mari yakawedzerwa ndeye kanenge 2 ‰ -3 ‰.
