Kodi obwezeretsedwa polima?

1. Kuyambitsa kusinthidwa polmer ufa (RDP)

Kubwezeretsedwa Polimer Polyder. Akasakanizidwa ndi madzi, mahoteli a RDP amalumikizana ndi lambi, ndikupereka mawonekedwe ofananawo monga kubalalitsidwa koyambirira. Zimawonjezera chotsatira, kusinthasintha, madzi kukana, komanso kulimba kwambiri kwa zinthu zamankhwala.

RDP makamaka imapangidwa ndi vinyl acetate ethylene (Vae), acrylic, kapena styrene-butadiene aprormers. Zinthu zake zimapangitsa kuti zikhale zofunikira pakupanga magwiridwe antchito ambirichosakanizamatope, zomata za matabwa, ndi njira zopirira kunja (magwiritsidwe apanja).

2. Kupanga

Kupanga kwa RDP kumakhudza njira zotsatirazi:

1. Polimeme emulsion kupanga: Oyambira ngati Vae amapangidwa kudzera mu emulsion polymerization.
2. Kuphatikiza: Kuteteza Colloids (mwachitsanzo, mowa wa polyvinyl) ndi anti-anti-ogwiritsa (mwachitsanzo, silica) amawonjezeredwa.
3. Kuwuma: Elymer emulsion ndi youma kuti apange ufa waulere.
4. Cakusita: Ufa umadzaza mu chinyezi chopanda chinyezi kuti chisunge katundu wake.

3. Mitundu ndi kapangidwe ka mankhwala

RDP imasiyanasiyana malinga ndi mtundu wa polymer ndi zowonjezera zamankhwala omwe amagwiritsidwa ntchito. Tebulo lotsatira likuwonetsera mitundu wamba ndi mawonekedwe awo oyamba:

Zowonjezera:

• Zoteteza ma colloids: Kumwa mowa kwa polyvinyl kumatsimikiziranso kukonzedwanso.
• Anti-Caking: Silica amalepheretsa kutseka.

4. katundu ndi mapindu

RDP imathandizanso zinthu zomangamanga popereka zinthu zotsatirazi:

Makina

• Kusinthasintha: Amachepetsa kusokonekera pazogulitsa za simenti.
• Chosangalatsa: Kumawonjezera kulumikizana m'malo osiyanasiyana.
• Kulimba kwamakokedwe: Kuchulukana kukana mphamvu zakunja.

Katundu wathupi

• Kusungidwa kwamadzi: Amachepetsa madzi, kuwonjezera hydration.
• Kugwirisetsa: Amathandizira kugwiritsa ntchito kosavuta komanso kumachepetsa.
• Kulimba: Kuchulukitsa kukana kuthengo ndi kuzizira.

5. Ntchito pamakampani

RDP imapeza ntchito m'magawo osiyanasiyana, makamaka zomanga.

Zipangizo Zomanga

• Zilonda za Tile ndi Zopukutira: Onetsetsani kutengera champhamvu komanso kukana kukana.
• Zodzikongoletsera zokha: Amasintha katenthedwe kake ndi kumaliza.
• Ma plakumas ndi matembenuzidwe: Zimakulitsa kugwiritsidwa ntchito komanso kukhazikika.

Makina Okhazikika

• Maupangiri (omaliza omaliza akunja): Amapereka kusinthasintha ndi kutsatira.

Mankhwala othandiza

• Zokutira ndi nembanemba: Kuwongolera madzi kukana ndi kuwonongeka.

Konzani matope

• Kukonza: Akumapangitsa mphamvu yopanga ntchito yobwezeretsa.

Gome: Mapulogalamu ndi Magwiridwe Ntchito

6. Magwiridwe antchito pomanga

Zothandiza za RDP ku zinthu zomanga zimatha kusanthula pamankhwala ake.

6.1 Adteion ndi Coutheon

• RDP imawonjezera mphamvu ya matope kwa matope magawo osiyanasiyana, kuphatikiza konkriti, nkhuni, zitsulo.

6.2 kusunga madzi

• Kusungidwa kwamadzi mothandizidwa kumathandizira zabwino za simenti ndi kugwirira ntchito.

6.3 kukana

• Kutupa komwe kumaperekedwa ndi RDP kumalepheretsa ming'alu chifukwa cha matenthedwe ndi makina.

Kusanthula matope okha ndi opanda rdp

7.. Misika ndi zinthu zina

Msika wa RDP padziko lonse lapansi ukukula, woyendetsedwa ndi kuchuluka kwa zinthu zomanga mphamvu ndi zolimbitsa thupi. Zochita zazikulu zikuphatikiza:

• Zogulitsa za Eco: Kukula kwa RDP yokhala ndi ma voc otsika (osasunthika) mpweya) mpweya.
• Mapangidwe apamwamba: Zatsopano mu Curyolymer zimayambitsa zovuta.
• Kukula kwamisika yamadzulo: Kukula koopsa ku Asia-Pacific ikulimbikitsa.

Gome: Kukula kwa msika wapadziko lonse lapansi

8. Zovuta ndi Zofooka

Ngakhale ndizabwino zake, RDP ili ndi zofooka zina:

• Kumverera kwa chinyezi: Pamafunika chinyezi chopanda chinyezi.
• Mitengo: RDP yapamwamba kwambiri imatha kuwonjezera mtengo.
• Mphamvu ya chilengedwe: VOC, ngakhale adatsitsidwa m'makono.

Kubwezeretsa polima polima ndi chinthu chofunikira kwambiri m'magawo amakono omanga, kupereka magwiridwe othandiza chifukwa cha kutsatira masinthidwe, kusinthasintha, ndi kukana madzi. Zosasintha zomwe zikupitilira komanso kukankha kwapadziko lonse lapansi zomangira zomangamanga zikuyembekezeredwa kupititsa patsogolo kukhazikitsidwa kwa ma rdp. Monga mafakitale amayang'ana mafakitale, kukhazikika, komanso kukhazikika kwachilengedwe, RDP ipitilizabe kuchita mbali yovuta kwambiri yopitilira tsogolo la zinthu zomanga.
