Ruzivo rwekutanga rwekuparadza polymer poda

1. Basic Pfungwa

Dzokorora polymer podandiyo inonyanya kuwanda yeiyo yakaoma poda yakagadzirira-yakasanganiswa motsi senge simende-yakavakirwa kana gypsum-yakavakirwa.

Dzokorora rondedzero yeLatex ndeye powder ndeye polymer emulsion iyo inosvitswa-yakaoma uye yakaunganidzwa kubva kuChigiri yekutanga kuumba masperi e80 ~ 120um. Nekuti nzvimbo dzezvikamu zvevakachinjika neisoric, hard-distas-kuramba hupfu, tinowana polymer yakaoma polymer. Ivo vari nyore kwazvo kudurura nebhegi rekuchengetedza mumuchengetedzo. Kana hupfu hwakasanganiswa nemvura, simende kana gypsum-based forar, inogona kudzoreredzwa, uye zviyero (2um) mairi ichaumbwa mune yekutanga latex, saka inonzi redisperslexix yeLatex.

Iyo ine rengozi yakanaka, inopararira zvakare mukurumbira wekusangana nemvura, uye ine chaiyo yakafanana makemikari emagetsi emberi. Nekuwedzera Polymeble Polymer poda kune coment-yakavakirwa kana gypsum yakaoma poda yakagadzirira-yakavhenganiswa mota, dzakasiyana-siyana dzenyama dzinogona kuvandudzwa, senge:

Kuvandudza kuderedza uye kubatana kwerufu;

Kuderedza mvura yekumira yezvinyorwa uye iyo elastic modulus yezvinyorwa;

Simba rinoslipera, zvinokanganisa kuramba, kurwisa abrasion kuramba uye kusimba kwekusimbisa zvinhu;

Kuvandudza mashandiro ekuvaka kwezvinhu, nezvimwe

2. Mhando dzekuparadza polymer polymer polymer

Parizvino, mainini ekushandisa mumusika anogona kukamurwa mukupararira lasix:

Vinyl acetate uye ethylene Copymer rubber poda Veeva Veova), vinyl acetate homopolymer rubber poda

3. Kuumbwa kwekuparadza Polymer poda

Pfuurira Polymer Polymer Poller inowanzo kuve chena poller, asi vashoma vane mamwe mavara. Zvinosanganiswa zvaro zvinosanganisira:

Polymer Resin: Iyo iri muchikamu chepakati yerabha yebhuruu, uye zvakare ndiyo chinhu chikuru cheiyo inotungamirwa polymer poymer.

Inowedzera (yemukati): pamwe chete neiyo resin, inotaridza basa rekugadzirisa iyo resin.

Kuwedzera (Kunze): Zvimwe zvinhu zvinowedzerwa kuti uwedzere kuwedzera kuita kwekuita kweiyo polymer polymer poda.

Dziviriro COLLID: Chikamu cheHydrophilic zvinhu zvakaputirwa pamusoro peiyo redispersle latex Powa Sceles, iyo colloid yeyakawedzera redxy latex hupfu muPolyvinyl doro.

Anti-caking agent: akanyatsoita kuti adzivirire iyo rabha pwere kubva pakuchengetwa uye kufambisa kuyerera kwerabha yebhuruu (kurira kubva pamapepa emapepa kana matangi).

4. Basa rekuparadza Polymer poda mudhiri

Iyo Reverpersible Latex poda inopararira mune iyo firimu uye inoita seinosimbisa mumiririri seyechipiri kuomerera;

Iyo colloid inodzivirira inoshatiswa nehurongwa hwekufa (hadzizoparadzwi nemvura mushure mekuumbwa kwemafirimu, kana "sekondari kupararira";

Iyo firimu-yekugadzira polymer inoparadzaniswa muhurongwa hwese senzira yekusimbisa, nekudaro achiwedzera kubatana kwemutya;

5. Basa rekuparadza polymer poda muguriri rakanyorova:

Kugadzirisa kushanda kwekuvaka;

Kuvandudza kuyerera zvivakwa;

Kuwedzera thiskotropy uye sag kuramba;

kuvandudza kubatana;
