Zomwe zimabwezeretsedwa polima

Kubwezeretsedwa Polider (RDP) ndi chinthu chofunikira kwambiri m'magawo amakono amakono, kupereka zida zophatikizika pamitundu yosiyanasiyana. Ndi mawonekedwe ake apadera komanso kugwiritsa ntchito mosiyanasiyana, Rdplays gawo lofunikira pokonza magwiridwe, kukhazikika, komanso kukhazikika kwa zinthu zomanga.

1. Kuyambitsa kusinthidwa polima

Ufa wobwezeretsedwa ndi ufa ndi ufa woyenda bwino, woyera womwe umapezeka m'mapulogalamu osokoneza bongo a polymer. Ufa uwu umakhala ndi kuphatikiza kwa opanga ma poizoni monga vinyl acetate ethylene (Vae), Vinyl acetate / Vinvan acetate / Vinyl chloride (e-vy), ndi ena. Njira yopanga imaphatikizapo kutembenuka kwa madzi obalalika mu mawonekedwe olimba a ufa pomwe amasunga polymer yawo.

2. Chemistry of Resistoreper Polymer ufa

Maminita a Drp amazungulira polymerization wa monomers kuti apange mabala okhazikika a polymer, omwe pambuyo pake amapukutidwa kuti apeze ufa wa ufa. Zinthu zazikulu zimapangitsa kuti katundu wa indenceter:

Kuphatikizika kwa polymer: ma polima osiyanasiyana amapereka zinthu zosiyanasiyana monga kusinthasintha, kotsatira, ndi kukana madzi. Mwachitsanzo, RPPS yochokera ku VAE imadziwika bwino kwambiri chifukwa cha kutsatira kwawo.

Othandizira a Crossling: Othandizira am'mphepete amatha kukulitsa madzi kukana ndi mphamvu yamagetsi ya RPP. Omwe amatola wamba amaphatikizapo aziridinectional Aziridines ndi Di-Isoctaneates.

Zowonjezera: Zowonjezera ngati zodetsa, zowonjezera, ndipo ma pulasitala nthawi zambiri amaphatikizidwa kuti athe kufalitsa kukhazikika, kalengedwe kamene kamapangidwe, komanso kusinthasintha kwa ziphuphu.

3. Kupanga njira yobwezeretsera polmer

Kupanga kwa Ndp kumaphatikizapo magawo angapo:

Polymerization: Moomments ndi polymer mu madzi am'madzi pansi pa malo olamulidwa kuti apange bata.

Kusintha kwa polymerization: Mankhwala owonjezera, monga zoteteza ma colloids kapena owotcha, atha kuwonjezeredwa kuti agwirizane ndi katundu wa kubala kwa polymer.

Kuwuma kwa Spray - Kubala kwa polymer kumavomerezeka kukhala madontho abwino ndikuwuma mumtsinje wotentha kuti upange tinthu tokhazikika. Njirayi imatsimikizira kusungidwa kwa polima potembenuza kubalaku kukhala ufa waulere.

4. Mapulogalamu a polmer polmer ufa

RDP imapeza zogwiritsidwa ntchito kwambiri m'mafakitale ndi ntchito:

Ntchito yomanga: RDP ndi gawo lofunikira mu mawonekedwe a zomata monga mataoma, mankhwala odzipereka, mabongo, ndi zopota. Zimasintha motsatira mawu, kusinthasintha, madzi kukana, komanso kugwirira ntchito izi.

Utoto ndi zokutira: RDP imathandizira mapangidwe a filimuwo, zomata, komanso kulimba kwa utoto wochokera m'madzi ndi zokutira. Imagwiranso ntchito ngati rheology yosintha, kukonza zomwe zimagwiritsidwa ntchito.

Zolemba: M'makampani opanga malembawo, RDP imagwiritsidwa ntchito ngati khola la nsalu zopanda chidwi, kupereka mphamvu, kusinthasintha, ndikusambitsa kukana zomaliza.

Mankhwala ogulitsa: RDP imagwira ntchito yokhazikika komanso yolumikizira mankhwala opanga mankhwala, imathandizira kumasulidwa ndikuwongolera bioavailability ya zosakaniza.

5. Ubwino wa Polmer Polmer

Kugwiritsa ntchito rdp kumapereka zabwino zambiri:

Zotsatsa zokulitsa: RDP imawonjezera chotsatsa cha zinthu zomanga ku magawo magawo osiyanasiyana, chifukwa champhamvu komanso zolimba.

Kusinthasintha kusinthika: kuwonjezera kwa rdp kumapangitsa kusinthasintha kumakulidwe, kuchepetsa chiopsezo cha kuwonongeka ndikuwongolera kulimba kwa zinthu.

Kukaniza Madzi: RDP imapereka madzi abwino kwambiri, ndikupanga kukhala koyenera kugwiritsa ntchito kunja komanso malo onyowa.

Kugwira ntchito: RDP imawongolera kugwirira ntchito komanso kusasamala kwa zinthu zomanga, kulola kuti pakhale kugwiritsa ntchito bwino ntchito komanso zowonjezera.

Kukhazikika: RDP imathandizira kupanga zinthu zachilengedwe kukhala ochezeka mwa kuchepetsa kugwiritsa ntchito zingwe zachikhalidwe ndikusintha moyo wa zomangamanga.

6. Zochita zamtsogolo

Tsogolo la LDP ligona mu kafukufuku ndipo nditayamba kukulitsa zinthu zake ndi ntchito zake. Madera ofunikira oyang'ana nawonso:

Kukula kwa Zoyenera: Kuyesetsa kukupangitsani kukhala ndi ma rdp kupangira zinthu zosinthidwa zosinthidwa ndi njira zochezera za eco-ochezeka kuti muchepetse zachilengedwe.

Zowonjezera zowonjezera

Mapangidwe osinthika: Phula la RDP kuti likwaniritse zofunika kudziwa kuti ndizofunikira kwambiri zomwe zikupitilirabe, kulola kusinthasintha kwakukulu ndi magwiridwe antchito osiyanasiyana.

7. Kumaliza

Ufa wobwezeretsedwayo umagwira ntchito yofunika kwambiri m'magulu amakono amakono, kupereka zomatira bwino, kusinthasintha, madzi kukana, ndi kulimbikira. Ndi umagwirira ntchito yake yapadera, kapangidwe kake, komanso kugwiritsa ntchito mosiyanasiyana, rdp kumangirizidwa kuyendetsanso zatsopano mafakitale osiyanasiyana. Mwa kumvetsetsa njira, kupanga, kugwiritsa ntchito, komanso mapindu a RDP, otenga nawo mbali amatha kuyamwa zinthu zolimba kuti zipangitse tsogolo lokhazikika.
