The ash content kubva nguva dzoseredispersible polymer podafekitori inowanzoita 10±2
Iyo ash yemukati mwero iri mukati me12%, uye mhando nemutengo zvinofananidzwa
Mamwe mapoda emumba anodarika 30%, uye mamwe mapoda erabha ane 50% madota.
Ikozvino mhando uye mutengo wepolymer poda inorasika pamusika hazvina kuenzana, edza kusarudza
Low ash content, high cost performance uye yakagadzikana mhando yekugovera.
Maitiro ekusarudza redispersible latex poda, kazhinji hazvigoneke kutanga kana uchigadzira fomula,
Hapana nzira inoshanda kunze kwekuiisa muchigadzirwa chekuyedza.
Kusarudzwa kweakakodzera disperible polymer poda inofanirwa kutariswa kubva pane zvinotevera zvinhu:
1. Iko kushanduka kwegirazi tembiricha yepolymer inoparara.
Iyo tembiricha yekuchinja kwegirazi ndiyo polymer inoratidza elasticity;pazasi tembiricha iyi, iyo polymer inoratidza brittleness.
Kazhinji, tembiricha yegirazi yekuchinja ye latex poda ndeye -15±5℃.
Chaizvoizvo hapana dambudziko.
Iyo tembiricha yegirazi yekuchinja chiratidzo chikuru chehunhu hwezvinopararira polymer hupfu, uye kune chaiwo zvigadzirwa,
Kusarudzwa kunonzwisisika kwegirazi rekuchinja tembiricha redispersible polymer poda inobatsira mukusimudzira chigadzirwa kushanduka uye kudzivirira.
kuputika, nezvimwewo.
2. Minimum film kugadzira tembiricha
Mushure meiyo inodhindwa uye inodhindwa yepolymer poda yakasanganiswa nemvura uye zvakare emulsified, ine zvinhu zvakafanana kune yekutanga emulsion.
Ndiko kuti, mushure mokunge mvura ichiputika, firimu ichaumbwa, iyo ine kushanduka kwepamusoro uye kunamatira kwakanaka kune akasiyana-siyana substrates.
Iyo yakaderera firimu-inogadzira tembiricha ye latex poda inogadzirwa nevagadziri vakasiyana ichave yakati siyanei.
Indekisi yevamwe vanogadzira i5 ℃, chero bedzi latex poda ine mhando yakanaka ine tembiricha yekugadzira firimu iri pakati pe0 ne5 ℃.
3. Redissolvable properties.
Yakaderera disperible polymer hupfu inonyungudika zvishoma kana kusatombonyungudika mumvura inotonhora kana alkaline mvura.
4. Mutengo.
Izvo zvakasimba zvemu emulsion zvinenge 53%, izvo zvinoreva kuti inenge 1.9 matani emulsion inosimbisa mune imwe toni yehupfu yerabha.
Kana iwe ukaverenga 2% yehuwandu hwemvura, iyo 1.7 matani emulsion kugadzira tani imwe yehupfu yerabha, pamwe negumi muzana yemadota,
Zvinotora anenge 1.5 matani emulsion kugadzira tani imwe yehupfu yerabha.5. Aqueous solution ye latex powder
Kuti uedze kutaridzika kweiyo redispersible latex poda, vamwe vatengi vanongonyungudutsa latex poda mu.
Ndichipedza kubvongodza mvura ndakaiyedza neruoko ndikaona isina kunamira ndikafunga kuti yaisava latex powder chaiyo.
Muchokwadi, redispersible latex poda pachayo haina kunamira, inoumbwa nekupfapfaidza kuomeswa kwepolymer emulsion.yehupfu.
Kana iyo redispersible polymer poda yakasanganiswa nemvura uye zvakare emulsified, ine zvinhu zvakafanana neiyo yekutanga emulsion, ndiko kuti, mwando.
Mafirimu akaumbwa mushure mekubuda kwemhepo anochinjika zvakanyanya uye anonamatira zvakanyanya kune akasiyana substrates.
Inogonawo kuwedzera kuchengetwa kwemvura yezvinhu uye kudzivirira dhaka resimende kubva pakuoma, kuoma uye kuputika nekukurumidza;
Wedzera plasticity yedhaka uye uvandudze kushanda kwekuvaka.Kana kuedza kuchizoitwa, kunofanira kunge kwakaenzana
Ita iyo dhaka retest kuti uone kupararira kwayo, kuumbwa kwefirimu, kuchinjika (kusanganisira kudhonza-kunze bvunzo,
Pasinei nokuti simba rekutanga rakakodzera) Kazhinji, migumisiro yekuedza inogona kuwanikwa mushure memazuva gumi
