Wobwezeretsedwa Polider Polyder (RDP)ndi mawonekedwe ophatikizika a lasex omwe amatha kukhala odzikuza ndi madzi kuti apange bata. Nthawi zambiri imagwiritsidwa ntchito pomanga, makamaka pakupanga zomatira, zopota zamafuta, utoto, ndi zokutira. Ufa umapereka mapindu osiyanasiyana, monga kusintha kusinthasintha, kutsatira, madzi kukana, ndi kulimba.
1. Polymer (gawo lalikulu)
Chofunikira chofunikira pakubwezeretsa polima ndi polymer, chopangidwa ndi acevinyl acetate (pva), styrene-yaniene rabara (sbrlene), kapena kuphatikiza kwa izi. Polymer amapanga msana wa obalalika pomwe ufa umakhala ndi matenda.
Polyvinyl Acetate (PRA):Nthawi zambiri amagwiritsidwa ntchito pomatira ndi zokutira chifukwa cha zomatira zake zamphamvu.
Styrene-butadiene mphira (SBR):Chofala pantchito zomanga chifukwa cha kusinthasintha ndi kulimba.
Ethylene-vinyl acetate (Eva):Amadziwika chifukwa cha kuchuluka kwake komanso zomatira, nthawi zambiri zimagwiritsidwa ntchito pogwiritsa ntchito kusinthasintha.
Udindo:Madzi akawonjezeredwa ku ufa, mamolekyulu a polymer amangotaya mtima ndikupanga kufalikira kokhazikika, kupereka mphamvu zamagetsi monga kutsatira, kusinthasintha, ndi kukana madzi.
2. Zogwiritsa ntchito (obalalitsa)
Ogwiritsa ntchito ndi mankhwala omwe amathandizira kukhazikitsa ufa wa latx, ndikuwonetsetsa kuti ingokhalabe m'madzi mutatha kukhala ndi matenda. Amachepetsa kuchepa kwa nkhope pakati pa tinthu tating'onoting'ono, kumathandizira kufalikira ndikuwongolera magwiridwe antchito a ufa.
Zosagwirizana:Izi nthawi zambiri zimagwiritsidwa ntchito kukhazikika kubalaku popanda kusokoneza mlandu wa ionic.
Anionic Zorfactonts:Thandizo lopewa kusokoneza kwa tinthu ndikuwongolera kubalalika kwa tinthu tating'onoting'ono.
Cationic Surfactants:Nthawi zina amagwiritsidwa ntchito pogwiritsa ntchito kafukufuku wapadera pomwe mtengo wake umafunikira kuti ugwire ntchito yabwinoko.
Udindo:Orfactonts amathandizira kuonetsetsa kuti ufa ukhoza kukhala wokhoza kukhala bwino kwambiri kukhala wosalala, wokhazikika wopanda kuponyera kapena kubisa.
3. Okhazikika
Okhazikika amawonjezeredwa ku ma pollmer Polymer kuti alepheretse tinthu tating'onoting'ono (chodulira limodzi). Amawonetsetsa kuti ufa utasakanizidwa ndi madzi, kufalikira kwa chifukwa chake kumakhala yunifolomu.
Polyethylene Glycol (Peg):Chitani chofala chomwe chimathandiza kusunga chosasinthika.
Cellulose zochokera:Nthawi zina amagwiritsa ntchito kukhazikika ndi mafayilo obalalika.
Nthali Yosinthidwa Kwambiri:Izi zimatha kukhala ngati okhazikika pamapangidwe ena kuti muchepetse kuphatikizika kwa tinthu.
Udindo:Kutsutsa ndikofunikira kuti muchepetse mtundu wa ma alhydartiction atch, onetsetsani kuti ndalama ndi zosinthasintha.
4.
Mafwereza ndi zida zowonjezeredwa ku ufa wa latex kuti muchepetse ndalama, sinthani zinthu zina, kapena sinthani kapangidwe kazinthu zomaliza. Izi zimaphatikizapo zinthu ngati calcium carbonate, talc, ndi silica.
Calcium carbonate:Nthawi zambiri amagwiritsidwa ntchito ngati filler kuti muwonjezere zambiri ndikupereka njira zokwanira muzosalonda ndi zokutira.
Talc:Ntchito pokonzanso maluwa ndikuwongolera mafayilo a malonda.
Silica:Imatha kukonza zopangira makina ndi kukana kwa zikwangwani zomaliza.
Udindo:Makonda osefera nthawi zambiri amawonjezeredwa kuti asinthe za rheilogical zopezeka kumapeto kwa latex, sinthani kuwongolera, ndikuwongolera kapangidwe komaliza.
5.. Oteteza
Kugwiritsa ntchito zoteteza kumaphatikizidwa ndikupanga kukula kwa microbial nthawi yosungirako ndikukhazikika kwa malonda kwakanthawi. Zosungidwa zodziwika bwino zimaphatikizapo methylisothiazolinone, benzosothiazorinone, ndi ma formaldehhyde-omasulidwa.
Methylisothiazolinone (Mit):Chotetezedwa chomwe chimalepheretsa kukula kwa ufa.
Benzisothiazolinone (pang'ono):Zofanana ndi Mit, zimalepheretsa fungal ndi bakiteriya.
Udindo:Operekera mabizinesi akuwonetsetsa kuti nthawi yopumira komanso kukhazikika kwa polimature polimalo nthawi yosungirako, kupewa kufooka kapena kudetsedwa.
6. Othandizira
Ogwiritsa ntchito ogwirizana ndi mankhwala omwe amathandizira tinthu tating'onoting'ono tomwe timachita bwino kwambiri pamene kubalalitsidwa kumayikidwa pa gawo lapansi. Amasintha mapangidwe a mafilimu, kupanga zomaliza zolimba komanso zosalimbana ndi kung'amba.
2,2,4-trimethyl-1,3-pentazeenuol:Coalescent wamba yomwe imagwiritsidwa ntchito kukonza mafayilo am'mawonekedwe mu emulsions.
Butyl Carbitol Acetate:Amagwiritsidwa ntchito pazogulitsa zina za latex kuti ziziyenda bwino komanso mawonekedwe a makanema.
Udindo:Othandizira ogwirizana amasintha magwiridwe antchito a latex kubalalitsidwa, kuonetsetsa kuti kumapanga filimu yosalala, yamphamvu pansi.
7..
Mapulasitiki amagwiritsidwa ntchito posintha kusinthasintha ndi kugwirira ntchito ufa wobwezeretsedwayo mukangoyikidwa komanso kuwuzidwanso. Amachepetsa kutentha kwagalasi (TG) ya polymer, kupanga zomaliza zosinthasintha.
Di-2-ethylhexyl phtate (dehp):Phukusi wamba lomwe limagwiritsidwa ntchito muzinthu zosiyanasiyana za latex.
Tri-N-Butyl Citrate (TBC):Nthawi zambiri amagwiritsidwa ntchito ngati pulasitiki yopanda poizoni pakupanga mapulogalamu.
Udindo:Mapulogalamu owonjezera mafayilo osinthika a Frahydrated Bayiction, kukonza kuthekera kwake kupirira kusokonekera ndi kusokoneza pakapita nthawi.
8.PHSTERSTERS
Zolowera PH zimawonjezeredwa ku mawonekedwe owonetsetsa kuti a Latx imasunga Ph, yomwe ndikofunikira kuti zibalalike mokhazikika komanso kugwirira ntchito kwa zinthu zina.
Ammonium hydroxide: Nthawi zambiri amagwiritsa ntchito kusintha Ph m'mapanga omaliza.
Sodium hydroxide: Amakonda kuwonjezera ph ngati pangafunike.
Udindo:Kusungabe woyenera kumatsimikizira kukhazikika kwa mafoni a Charasex, monga ma ph kwambiri amatha kuyambitsa kuchepa kapena kusakhazikika pakupanga.

BDPNdi zinthu zosiyanasiyana zomwe zimagwiritsidwa ntchito kwambiri pomanga ndi zokuthandizani, chifukwa chogwira mtima kuti azipanga zinthu zosiyanasiyana. Chilichonse, kuchokera polymer kwa okhazikika kwa okhazikika komanso okonda kupanga, amatenga gawo lofunikira pakuwonetsetsa kuti ufa umabalalika mosavuta m'madzi, zolimbitsa thupi zolimbitsa thupi. Kumvetsetsa maudindo ndi ntchito za zinthu zomwe zopangira izi ndizofunikira kuti mukwaniritse magwiridwe awo mu mapulogalamu osiyanasiyana, kaya azosala, utoto, kapena zimbudzi.
