Nezve dambudziko iro putty poda iri nyore kuita hupfu, kana simba harina kukwana.Sezvatinoziva tose, cellulose ether inoda kuwedzerwa kuita putty powder, HPMC inoshandiswa kumadziro putty, uye vashandisi vazhinji havawedzere redispersible latex powder.Vanhu vazhinji havawedzere hupfu hwepolymer kuitira kuchengetedza mutengo, asi ichi zvakare kiyi yekuti nei yakajairwa putty iri nyore kuita hupfu uye inotarisana nezvinetso zvemhando yechigadzirwa!
Ordinary putty (senge 821 putty) inonyanya kugadzirwa nehupfu chena, diki starch glue uye CMC (hydroxymethyl cellulose), uye mamwe anogadzirwa nemethyl cellulose uye Shuangfei hupfu.Iyi putty haina kunamatira uye haina kudzivirira mvura.
Cellulose inogona kutora mvura uye kuzvimba mushure mekunyungudutswa mumvura.Zvigadzirwa kubva kune vakasiyana vagadziri vane mazinga akasiyana ekutora mvura.Cellulose inobata basa mukuchengetedza mvura mu putty.Iyo yakaomeswa putty ine rimwe simba kwenguva pfupi, uye inozodzima zvishoma nezvishoma mushure menguva refu.Izvi zvine hukama zvakanyanya neiyo molecular chimiro che cellulose pachayo.Putty yakadaro haina kusimba, inosveta mvura yakawanda, iri nyore kupwanya, haina simba, uye haina kusimba.Kana topcoat yakaiswa pamusoro, yakaderera PVC iri nyore kuputika uye furo;yakakwirira PVC iri nyore kuderedza uye kuputika;nekuda kwekukwira kwemvura kunyura, zvinokanganisa kuumbwa kwefirimu uye mhedzisiro yekuvaka yetopcoat.
Kana iwe uchida kuvandudza matambudziko ari pamusoro peiyo putty, iwe unogona kugadzirisa iyo putty formula, kuwedzera imwe redispersible latex poda zvakakodzera kuti uvandudze simba rekupedzisira reputty, uye sarudza yakakwirira-mhando hydroxypropyl methylcellulose HPMC ine yakavimbiswa mhando.
Muchigadzirwa chekugadzira putty, kana huwandu hwehupfu hwehupfu hwakawedzera husina kukwana, kana kuti pasi pe latex poda yeputty inoshandiswa, chii chichava nemigumisiro paputty powder?
Kusakwana huwandu hweputty redispersible latex poda, chiratidziro chakananga ndechekuti iyo putty layer yakasununguka, iyo pamusoro yakanyungudika, huwandu hwependi inoshandiswa kugadzira topcoating ihombe, nzvimbo yekuenzanisa haina kunaka, iyo nzvimbo yakaoma mushure mekuumbwa kwefirimu, uye zvakaoma kuumba dense pendi firimu.Madziro akadaro anowanzoita kusvuura, kuputika, kusvuura, uye kutsemuka kwefirimu repende.Kana ukasarudza yakaderera putty powder, zviri pachena kuti magasi anokuvadza akadai se formaldehyde anogadzirwa pamadziro achakonzera kukuvadza mumuviri kune vamwe.
