n iyo chaiyo nharaunda yemusika, akasiyana marudzi e latex poda anogona kutsanangurwa seanopenya. Nekuda kweizvozvo, kana mushandisi asina ake ehunyanzvi matekinoroji kana midziyo yekuongorora, anogona kungonyengedzwa nevazhinji vatengesi vasina kutendeseka pamusika. Parizvino, kune dzimwe dzinonzi nzira dzekuona dzinotenderera paInternet, dzakadai se: kucherechedza turbidity yemhinduro yakanyungudika uye mamiriro ekugadzira firimu. Nzira idzi ndedzekuziva chete kubva pamusoro, uye haigone kupa tsigiro yesainzi nzira yekusimbisa kwekupedzisira kwemushandisi kana chigadzirwa chakakodzera kwaari. Naizvozvo, muchinyorwa chino, tichazivisa zvine hungwaru mamwe ekutanga pfungwa dzehupfu yerabha mahara kubva kune ekutanga magadzirirwo ezvakagadzirwa, maitiro, uye chinangwa chekushandiswa kwehupfu yerabha, kuitira kuti vatinoshanda navo vazvitongere ivo pachavo chakanaka uye chakanaka. defective.
Chekutanga, pfungwa yakakosha yekunzwisisa kuti iyo yechokwadi disperible polymer poda inogadzirwa sei. (Redispersible latex powder ipolymer powder ine redispersible properties iyo inoshandurwa kubva ku synthetic resin emulsion nekuwedzera zvimwe zvinhu uye sprayed-yakaomeswa. Kana mvura inoshandiswa senzira yekuparadzira, inogona kuumba emulsion uye ine redispersible polymer powder. Redispersible The latex powder inowanzova yeupfu chena, asi mashoma redisin powder anofanira kusanganisira mamwe mavara: additives, inodzivirira colloid, anti-caking agent. . Kuti ive nechokwadi chekugadzikana kwemhando yechigadzirwa, mafekitori makuru akajairwa anowanzo shandisa mhando yepolyvinyl acetate kugadzira redispersible polymer poda. Pano tinogona kutora muenzaniso unoshanda. Muna 2015, mhando inozivikanwa yemumba yehupfu yerabha yakatsiva iyo yakachipa yepolyvinyl acetate emulsion kuti igadzire redispersible polymer hupfu nekuda kwezvikonzero zvekutonga. Nekuda kweizvozvo, kuchinjika kwemhando huru kwakakonzerwa. yakakonzera kukuvara kusingagadzirike. Kunyangwe vamwe vatengesi vasina kutendeseka pano vachashandisa chena latex nezvimwe zvakadaro pane kupukuta huruva.
2. Additives (mukati) inoshanda pamwe chete neresin kugadzirisa resin, somuenzaniso, plasticizer inoderedza kupisa kwefirimu-kuumba resin (kazhinji vinyl acetate / ethylene copolymer resins haifaniri kuwedzera plasticizers), kwete yose latex Powder ine additives. Iyo redispersible latex poda yevazhinji vagadziri vadiki vane chete firimu inogadzira tembiricha index uye haigone kunzi tembiricha yegirazi yekuchinja, iyo zvakare yakakosha parameter yemhando yehupfu yerabha pachayo.
3. Protective colloid A layer ye hydrophilic material yakaputirwa pamusoro pezvinodzokororwa redispersible latex powder particles, uye muviri unodzivirira wezvizhinji zvinodhindwa zvakare latex powders ndeye polyvinyl doro. Iyo polyvinyl doro pano ndeye kutora chikamu mukupfapfaidza kuomesa pamwe chete, pane kungosanganisa. Heino imwe dambudziko rinowanzoitika mumusika. Mazhinji maworkshops anoti ari kugadzira rubber powder anongoita kusanganisa kwemuviri. maitiro, chigadzirwa ichi hachikwanisi kunyatsonzi dispersible polymer poda.
4. Zviwedzerwa (zvekunze) Zvishandiso zvinowedzerwa kuti zviwedzere kuwedzera kushanda kwemafuta ekupedzisira elatex, zvakadai sekuwedzera superplasticizers kune imwe fluidized latex powders. Kufanana nekuwedzera kwemukati, kwete marudzi ese ehupfu hwepolymer anodhindwa anoshandiswa. Latex powders ese ane chinowedzerwa ichi.
5. Anti-caking agent Fine mineral filler, inonyanya kushandiswa kudzivirira latex poda kubva mukuungana panguva yekuchengetedza uye kutakura uye kufambisa kuyerera kwelatex poda (yakakandwa kubva mumabhegi emapepa kana matangi). Iyi filler ndiyo zvakare chikamu chinozokanganisa zvakanyanya mutengo chaiwo wekugadzira uye kushanda kweiyo inorasika polymer poda. Mazhinji emitengo yakaderera erabha poda pamusika anowedzera reshiyo yekuzadza kuderedza mitengo. Zvichitaurwa zviri nyore, ndiyo chiratidzo chemukati madota chinowanzo kutaurwa nezvacho. Akasiyana mafirita akawedzerwa nevagadziri akasiyana anozokanganisawo musanganiswa wehupfu yerabha uye simende. Nekuti kusungirirwa kwema inorganic adhesives kune zvigadzirwa kunowanikwa kuburikidza nemusimboti wekumisikidza kwemakanika
