Kugadzirwa kweV-0 Flame-Retardant PVC Thermoplastic Plastics

Kugadzirwa kweV-0 Flame-Retardant PVC Thermoplastic Plastics

Kuti uwane chiyero cheV-0 flame retancy range (zvichienderana neUL-94 standards) mumapurasitiki ePVC ethermoplastic, aluminium hypophosphite neboric acid zvinhu zviviri zvinoshandiswa zvakanyanya flame retardants. Mazinga avo ekuwedzera anofanirwa kugadziriswa zvichienderana nekugadzirwa kwacho, mamiriro ekugadzirisa, uye zvinodiwa pakushanda. Heano mamwe mazano uye mareferensi:

1. Kuwedzera Kwehuwandu hweAluminium Hypophosphite

Aluminum hypophosphite inodzivirira moto inoshanda nephosphorus yakakodzera zvinhu zvePVC. Inodzivirira kupisa nekugadzira phosphate layer inodzivirira uye inoburitsa gasi rephosphoric acid.

• Danho rekuwedzera rinokurudzirwa: 15–25 ph.(zvikamu pazvikamu zana zve resin)
• Kune PVC yakajairwa, kuwedzera kumativi eseMakumi maviri emazwiyealuminium hypophosphite inowanzo svika pachiyero cheV-0 flame retardant.
• Kana moto usisashande zvakanaka, chiyero chinogona kuwedzerwa, asi kukanganisa kwazvinoita pahunhu hwemakanika kunofanira kufungwa nezvako.
• Zvekungwaririra:
• Kuwanda kwearuminiyamu hypophosphite kunogona kuderedza mashandiro ekugadzirisa (semuenzaniso, kusakwanisa kuyerera zvakanaka).
• Zvinokurudzirwa kuti zvisanganiswe nezvimwe zvinodzora moto (semuenzaniso, boric acid, aluminium hydroxide) kuti zvive nemigumisiro inoshanda pamwe chete.

2. Kuwedzera Boric Acid

Boric acid chinhu chinodzivirira moto chinodhura zvishoma chinoshanda zvikuru kuburikidza nekuora kwe endothermic uye kugadzirwa kwechikamu chinodzivirira chakaita segirazi.

• Danho rekuwedzera rinokurudzirwa: 5–15 ph.
• Boric acid inowanzo shandiswa sechinhu chinodzivirira moto, uye huwandu hwakawandisa hunogona kukanganisa mashandiro emuchina uye ekugadzirisa.
• MuPVC, kuwedzera kutenderedzaMapumburu gumiye boric acid inogona kushanda pamwe chete nealuminium hypophosphite kuti iwedzere kunonoka kwemurazvo.
• Zvekungwaririra:
• Boric acid haina hygroscopic, saka kuichengeta nekubata kwayo kunofanira kudzivirira kunyudzwa kwehunyoro.
• Kushanda kwayo kunodzivirira moto kunogumira pakushandiswa yoga; inowanzo sanganiswa nezvimwe zvinodzivisa moto (semuenzaniso, aluminium hypophosphite, aluminium hydroxide).

3. Kuumbwa kweAluminium Hypophosphite neBoric Acid pamwe chete

Kuti uwane chiyero cheV-0, aluminium hypophosphite neboric acid zvinogona kusanganiswa kuti zvive nemigumisiro yekubatana. Pazasi pane fomura yekutarisa:

• Aruminiyamu hypophosphate: 15–20 maprendi
• Boric acid: 5–10 maprendi
• Zvimwe zvinowedzera:
• Plasticizer (semuenzaniso, DOP): Sezvinodiwa (yakagadziriswa zvichienderana nezvinodiwa nekuomarara kwePVC)
• Chinosimbisa:2–5 mapr(semuenzaniso, munyu we lead, zvinosimbisa calcium-zinc)
• Mafuta ekuzora:0.5–1 phr(semuenzaniso, stearic acid)

Muenzaniso weKuumbwa:

• PVC resin:100 phr
• Aruminiyamu hypophosphate:18 phr
• Zinc borate:8 mapr
• Chinoisa purasitiki (DOP):40 phr
• Chinosimbisa:3 mapr
• Mafuta ekuzora:0.8 phr

4. Kuedza uye Kugadzirisa

Mukushandisa kwakakosha, matanho anotevera anokurudzirwa pakuedza nekugadzirisa:

1. Kuumbwa kwemutyairi wendege:Gadzirira bvunzo diki zvichienderana nematanho ekutarisa.
2. Bvunzo reUL-94:Ita bvunzo dzekupisa dzakamira kuti uone kana moto wacho wakaremara.
3. Kuedzwa kwekushanda:Ongorora hunhu hwemakanika (semuenzaniso, simba rekudhonza, simba rekukanganisa) uye mashandiro ekugadzirisa (semuenzaniso, kuyerera kwemvura, kugadzikana kwekupisa).
4. Kugadzirisa:Gadzirisa huwandu hwekuwedzera kwealuminium hypophosphite neboric acid kana kuisa zvimwe zvinodzora moto (semuenzaniso, aluminium hydroxide, antimony trioxide) kuti uwedzere kushanda.

5. Zvinhu Zvikuru Zvekufunga nezvazvo

• Kupisa kwekugadzirisa:Kupisa kwekuora kwealuminium hypophosphite neboric acid kwakanyanya; iva nechokwadi chekuti tembiricha dzekugadzirisa hadzipfuure miganho iyi kudzivirira kuora.
• Kupararira:Iva nechokwadi chekuti zvinhu zvinodzivisa moto zvakapararira zvakaenzana muPVC kudzivirira matambudziko ehuwandu hwemoto munzvimbo imwe chete.
• Kukanganiswa kwezvakatipoteredza:Zvese zviri zviviri aluminium hypophosphite neboric acid zvinodzivirira moto zvisina njodzi kunharaunda, asi zvinoenderana nezvimwe zvinowedzerwa zvinofanira kusimbiswa.

6. Mhedziso

Kuti uwane chiyero cheV-0 chekudzivirira moto mumapurasitiki ePVC ethermoplastic, mazinga ekuwedzera anokurudzirwa ndeaya15–25 phr yearuminiyamu hypophosphiteuye5–15 phr ye boric acidKushandiswa kwezvinodzivirira moto izvi pamwe chete kunogona kuwedzera mashandiro azvo. Muchokwadi, kugadzirisa kwacho kwakavakirwa pamafomu chaiwo uye zvinodiwa pakushanda kwakakosha, uye bvunzo dzeUL-94 dzinofanirwa kuitwa kuti dzionekwe kuti flame retardancy rating ndeyei.
