RDP Ndi VAE Powder

RDP (Redispersible Polymer Powder) ndi VAE (Vinyl Acetate Ethylene) Powder. Tiyeni tifufuze aliyense payekhapayekha:

RDP (Redispersible Polima Powder):

1. Tanthauzo:

• RDP ndi ufa woyera wosasunthika womwe umapezeka mwa kupopera-kuyanika emulsion ya polima. Chifukwa cha ufa akhoza mosavuta anabalalitsidwa m'madzi, kupanga filimu ya polima choyambirira.

2. Mapangidwe:

• Amapangidwa ndi polima (monga vinyl acetate-ethylene copolymer), colloid yoteteza, chobalalitsa, ndipo nthawi zina zowonjezera monga mapulasitiki kapena thickeners.

3. Kugwiritsa ntchito:

• RDP imagwiritsidwa ntchito kwambiri pantchito yomanga monga chowonjezera mu matope osakaniza owuma, monga zomatira matailosi, zodzipangira zokha, komanso matope okonza. Imawonjezera mphamvu zazinthu izi, kuphatikiza kumamatira, kulimba kwa flexural, ndi magwiridwe antchito.

4. Ntchito:

• Imawongolera kumamatira ku magawo osiyanasiyana.
• Kumawonjezera kusinthasintha ndi kupunduka.
• Amapereka mphamvu zosungira madzi.
• Imalimbitsa kukana kwanyengo ndi ukalamba.
• Imagwira ntchito ngati chomangira kuti chiwongolere zida zamakina amatope.

5. Ubwino:

• Amachepetsa kung'amba ndi kuchepa mumatope.
• Imakulitsa kulimba kwa zomangira zomalizidwa.
• Imawongolera magwiridwe antchito komanso kugwiritsa ntchito matope osakaniza owuma.

VAE (Vinyl Acetate Ethylene) Ufa:

1. Tanthauzo:

• VAE ufa ndi copolymer ya vinyl acetate ndi ethylene yomwe nthawi zambiri imapangidwa mu mawonekedwe a ufa. Imapezedwa ndi kupopera-kuyanika emulsion ya VAE.

2. Mapangidwe:

• Amakhala ndi vinyl acetate ndi ethylene copolymer, nthawi zambiri amakhala ndi zowonjezera zowonjezera kuti apititse patsogolo zinthu zina.

3. Kugwiritsa ntchito:

• VAE ufa nthawi zambiri amagwiritsidwa ntchito popanga zomatira, zosindikizira, komanso ngati chomangira popanga nsalu zopanda nsalu.

4. Ntchito:

• Amapereka zomatira mu zomatira ndi sealants.
• Amagwira ntchito ngati chomangira munsalu zosalukidwa.
• Kumawonjezera kusinthasintha ndi elasticity mu ntchito zosiyanasiyana.

5. Ubwino:

• Amapereka kumamatira kwabwino kwa magawo osiyanasiyana.
• Imakulitsa kusinthasintha komanso kukhazikika muzomatira zomatira.
• Itha kugwiritsidwa ntchito m'njira zosiyanasiyana chifukwa cha kusinthasintha kwake.

Kuyerekeza:

• Kufanana:
  • Onse a RDP ndi VAE ufa amachokera ku emulsions ndipo amagwiritsidwa ntchito nthawi zambiri muzomangamanga.
• Kugwiritsa Ntchito Mwachindunji:
  • RDP idapangidwa makamaka kuti igwiritsidwe ntchito mumatope osakaniza owuma, zomwe zimapangitsa kuti zikhale zomatira komanso zamakina.
  • VAE ufa uli ndi ntchito zambiri, kuphatikiza zomatira, zosindikizira, ndi nsalu zosalukidwa.
• Zolemba:
  • Ngakhale kuti zonsezi zimakhudzana ndi vinyl acetate, RDP nthawi zambiri imaphatikizapo zigawo zina monga zoteteza ma colloids, obalalitsa, ndipo nthawi zina zowonjezera.
• Ntchito:
  • RDP imathandizira makamaka magwiridwe antchito a zida zomangira, kuyang'ana kwambiri kumamatira, kusinthasintha, komanso kulimba.
  • VAE ufa umagwira ntchito zosiyanasiyana, kuphatikiza kupereka zomatira, kuchita ngati chomangira, ndikuwongolera kusinthasintha pazogwiritsa ntchito zosiyanasiyana.

Mwachidule, onse a RDP ndi VAE ufa ndi zida zamtengo wapatali pakugwiritsa ntchito kwawo, pomwe RDP imakhala yapadera kwambiri pazinthu zomanga, ndi ufa wa VAE wokhala ndi ntchito zambiri kuphatikiza zomatira, zosindikizira, ndi nsalu. Ngati muli ndi nkhani kapena ntchito inayake m'maganizo, khalani omasuka kupereka zambiri kuti muyankhe moyenera.
