Dzokorora polymer poda (RDP)Icho chimiro chakapetwa choseki chinonoka chinogona kuvhenekerwa nemvura kuti ugadzire kuparadzwa kwakasimba. Izvo zvinowanzoshandiswa mukuvaka, kunyanya muchimiro chezvinoshatirisa, marara makomba, pendi, uye huviri. Iyo hupfu inopa zvakaringana zvakanaka, sekuvandudza kushanduka, kuderera, kuramba kwemvura, uye kusimba.
1. Polymer (chikuru chikamu)
Iyo yakakosha Iyo polymer inoumba musana wekupararira kana hupfu hwacho hwakatsigirwa.
Polyvinyl acetate (PVA):Inowanzoshandiswa mumakonje uye machira nekuda kwezvivakwa zvaro zvinonetsa.
Styrene-butadiene Rubber (SBR):Zvakajairika mukushandisa kwekuvaka nekuda kwekushanduka kwayo uye kusimba.

Cationic surfachants:Dzimwe nguva inoshandiswa kune chaiyo mafaro okushandiswa kwakanaka kunodiwa mukubatanidza zviri nani.
Basa:SurfactVanti dzinobatsira kuve nechokwadi chekuti hupfu hunogona kuverengerwa nyore nyore kuita rakatsvuka, hwakagadzikana husina kuparadzaniswa pasina kudzima kana kuwanda.
3. Stabilizer
Stabilizer anowedzerwa kune dzinotsauka polymer polymer polymer yekudzivirira iyo latex zvimedu kubva kuAgglometer (clumping pamwe chete). Ivo vanoona kuti kana hupfu hwakasanganiswa nemvura, kuparadzwa kunobva kwatunifomu uye kugadzikana.
Polyethylene Glycol (Peg):Dhizaini rakajairika rinobatsira kuchengetedza kusawirirana.
Cellulose detivatives:Dzimwe nguva inoshandiswa kusimudzira kugadzikana uye viscosity yekupararira.
Hydrophobically yakagadziridzwa nyeredzi:Izvi zvinogona kuita seStabilizers mune zvimwe zvinhu zvekudzivirira kusvirana.
Basa:Stabilizer akakosha kuti uchengetedze huwandu hwekupararira kweiyo yakagadziridzwa laydrated latex, ichisimbisa kunyange kusawirirana uye kwakanaka mashandisiro ekushandisa.
4. Vafiler
Vafereya midziyo yakawedzerwa kune iyo latex poda kuti ideredze mitengo, kuvandudza zvimwe zvinhu, kana kushandura chimiro chechigadzirwa chekupedzisira. Izvi zvinosanganisira zvinhu kunge calcium kabhoni, talc, uye silika.
Calcium carbonate:Inowanzoshandiswa seye filer yekuwedzera yakawanda uye inopa mhinduro dzinodhura mukuzvinyudza uye nemakonzo.
Talc:Inoshandiswa pakuvandudza kuyerera uye kudzora iyo viscosity yechigadzirwa.
Silika:Inogona kuvandudza manhamba emuchina uye kukwenya kudzikisira kwechigadzirwa chekupedzisira.
Basa:Vafiridzi vanowanzowedzerwa kuti vagadzirise zvivakwa zvetsiva zvekupararira kweLatex, kugadzirisa maitiro, uye kudzora chimiro chekupedzisira.
5. Preservatives
Vanochengetedzwa vanosanganisirwa mune yekuumbwa kudzivirira kukura kwemicrobial panguva yekuchengetedza uye kuchengetedza kugadzikana kwechigadzirwa nekufamba kwenguva. Comment Preservatives inosanganisira methylasothizolinone, Benzisothiazolinone, uye formaldehyde-kusunungura vamiririri.
MethylorThiazolinone (mit):Chengetedza chakashandiswa zvakanyanya chinodzivirira kukura kwemachira mune hupfu.
Benzisothiazolinone (Bit):Yakafanana neye mit, inodzivirira fungul uye bacerial kusvibiswa.
Basa:Vanochengetedzeka vanoona kuti longevhity uye kugadzikana kweiyo redspersble polymer poda panguva yekuchengetedza, ichidzivirira kubva kushatirisa kana kusvibiswa.
6. MaAalescing Agents
Vatambi veCalalinecs vane makemikari anobatsira iyo latex zvimedu kuti fuse pamwe zvakanyanya zvinobudirira kana iyo yekupararira ichishandiswa kune substrate. Vanovandudza kugadzirwa kwemafirimu, vachiita kuti chigadzirwa chekupedzisira chakanyanya kusimba uye chinodzivirira kupfeka uye kubvarura.
2,2,4-trimethyl-1,3-pentanedeol:Mucherechedzo waizivikanwa wakashandiswa kugadzirisa kugadzirwa kwemafirimu mumhungu.
Butyl Carbitol acetate:Inoshandiswa mune imwe zvigadzirwa zve latex yekuyerera kuri nani uye kuumbwa kwemafirimu.
Basa:Vamiriri veCalalces vanovandudza mashandiro ekupararira kweLatex, anoona kuti inoumba firimu rakatsetseka, rakasimba pamusoro.
7. Plasticze
Mapurasitiki anoshandiswa kuvandudza kushanduka uye kushanda kweiyo redspersble polymer poda kana yaiswa uye yakagadzirwazve. Ivo vanodzikisa girazi transition tembiricha (TG) yePolymer, vachiita kuti chigadzirwa chekupedzisira chinja.
Di-2-Ethylhexyl Phthalate (DeHP):Iyo yakajairika plasticze inoshandiswa mune dzakasiyana siyana dzeLatex zvigadzirwa.
Tri-n-butyl Citrate (TBC):Inowanzoshandiswa seyisiri-ine chepfu epasi pane zvekuvaka zvekushandisa.
Basa:Mapurasitiki anowedzera kushanduka kweiyo yakagadziridzwa liverm ratex, ichivandudza kugona kwayo kuti isarambe ichipwanya uye deformation nekufamba kwenguva.
8.ph aformers
PH Achaders inowedzerwa kune iyo yekuumbwa kuti ive nechokwadi chekuti Latex inochengetedza iyo yakagadzikana pH, iyo yakakosha kune ese ari maviri kupararira kugadzikana uye kushanda kwezvimwe zvinoshandiswa.
Ammonium Hydroxide: Inowanzoshandiswa kugadzirisa pH mukuumbwa kwenzvimbo.
Sodium hydroxide: Yaishandiswa kuwedzera ph kana zvichidikanwa.
Basa:Kuchengeta wakakodzera PH anovimbisa kugadzikana kweiyo Latex kupararira, seyakanyanya pH mazinga inogona kukonzera kusvibiswa kana kusagadzikana mukuumbwa.
