Guhindura formulaire ya Halogen-Yubusa Flame Retardant PVC Uruhu

Guhindura formulaire ya Halogen-Yubusa Flame Retardant PVC Uruhu

Intangiriro

Umukiriya akora flame-retardant PVC uruhu kandi mbere yakoreshejwe antimoni trioxide (Sb₂O₃). Ubu bafite intego yo gukuraho Sb₂O₃ no guhinduranya halogen-flame retardants. Ubu buryo bukubiyemo PVC, DOP, EPOXY, BZ-500, ST, HICOAT-410, na antimoni. Inzibacyuho ivuye muri antimoni ishingiye kuri PVC y'uruhu kuri sisitemu ya halogen idafite flame-retardant yerekana kuzamura ikoranabuhanga. Ihinduka ntabwo ryubahiriza gusa amategeko agenga ibidukikije akomeye (urugero, RoHS, REACH) ariko kandi azamura ishusho "icyatsi" cyibicuruzwa no guhangana ku isoko.

Inzitizi z'ingenzi

1. Gutakaza Ingaruka Zihuza:
   • Sb₂O₃ ntabwo ari flame retardant yonyine ariko yerekana ingaruka nziza za synergistic flame-retardant hamwe na chlorine muri PVC, bizamura imikorere neza. Kuraho antimoni bisaba gushakisha ubundi buryo bwa halogen-sisitemu yigana ubu bufatanye.
2. Gukoresha Flame Gukora neza:
   • Halogene idafite flame retardants akenshi isaba imitwaro iremereye kugirango igere ku ntera ihwanye na flame-retardant (urugero, UL94 V-0), ishobora kugira ingaruka kumiterere yubukanishi (ubworoherane, imbaraga zingana, kuramba), imikorere yo gutunganya, nigiciro.
3. Ibiranga uruhu rwa PVC:
   • Uruhu rwa PVC rusaba ubworoherane buhebuje, kumva amaboko, kurangiza hejuru (gushushanya, kurabagirana), kurwanya ikirere, kurwanya kwimuka, hamwe nubushyuhe buke. Imiterere mishya igomba gukomeza cyangwa guhuza neza niyi miterere.
4. Imikorere yo gutunganya:
   • Imitwaro myinshi ya halogene ituzuye (urugero, ATH) irashobora kugira ingaruka kumashanyarazi no gutunganya neza.
5. Ibitekerezo:
   • Bimwe mubikorwa byo hejuru bya halogen-flame retardants bihenze, bisaba kuringaniza hagati yimikorere nigiciro.

Ingamba zo Guhitamo Halogen-Yubusa ya Flame Retardant Sisitemu (kuri PVC Uruhu rwa artificiel)

1. Ibirindiro byibanze bya Flame - Hydroxide Metal

• Aluminium Trihydroxide (ATH):
  • Byinshi mubisanzwe, birahendutse.
  • Mechanism: Kwangirika kwa Endothermic (~ 200 ° C), kurekura imyuka y'amazi kugirango igabanye imyuka yaka umuriro na ogisijeni mugihe ikora urwego rukingira.
  • Ingaruka: Gukora neza, gupakira cyane bisabwa (interuro 40-70), bigabanya cyane ubworoherane, kuramba, hamwe nibikorwa; ubushyuhe bwangirika ni buke.
• Magnesium Hydroxide (MDH):
  • Ubushyuhe bwo hejuru cyane (~ 340 ° C), bukwiranye no gutunganya PVC (160–200 ° C).
  • Ingaruka: Ibintu biremereye bisa (40-70 interuro) bikenewe; igiciro kiri hejuru gato ya ATH; irashobora kugira amazi menshi.

Ingamba:

• Hitamo MDH cyangwa ATH / MDH ivanze (urugero, 70/30) kugirango uhuze ibiciro, gutunganya ubushyuhe bwimiterere, hamwe no kutagira umuriro.
• Ubuso buvuwe (urugero, silane-bufatanije) ATH / MDH itezimbere ubwuzuzanye na PVC, igabanya iyangirika ryumutungo, kandi ikongerera umuriro.

2. Gukoresha Flame Retardant Synergiste

Kugabanya imitwaro yibanze ya flame retardant no kunoza imikorere, synergiste ni ngombwa:

• Fosifore-Azote Flame Retardants: Nibyiza kuri sisitemu ya PVC ya halogene.
  • Ammonium Polyphosphate (APP): Itezimbere kwishyuza, ikora urwego rukingira.
    • Icyitonderwa: Koresha amanota arwanya ubushyuhe bwinshi (urugero, Icyiciro cya II,> 280 ° C) kugirango wirinde kubora mugihe cyo gutunganya. APP zimwe zishobora kugira ingaruka kumucyo no kurwanya amazi.
  • Aluminium Diethylphosphine (ADP): Gukora neza cyane, gupakira bike (interuro 5–20), ingaruka nkeya kumitungo, ituze ryiza ryumuriro.
    • Ingaruka: Igiciro kinini.
  • Fosifate Esters (urugero, RDP, BDP, TCPP): Imikorere nka plastike yumuriro.
    • Ibyiza: Inshingano ebyiri (plastizer + flame retardant).
    • Ibibi: molekile nto (urugero, TCPP) irashobora kwimuka / guhindagurika; RDP / BDP ifite ubushobozi buke bwo gukora plastike kurusha DOP kandi irashobora kugabanya ubushyuhe buke.
• Zinc Borate (ZB):
  • Igiciro gito, gikora cyane (flame retardant, suppressant, umwotsi wa char, anti-daming). Guhuza neza hamwe na sisitemu ya ATH / MDH na fosifore-azote. Ibisanzwe bisanzwe: 3-10 interuro.
• Stancate ya Zinc / Hydroxy Stannate:
  • Kurwanya umwotsi mwiza hamwe na flame retardant synergiste, cyane cyane kuri chlorine irimo polymers (urugero, PVC). Irashobora gusimbuza igice uruhare rwa antimoni. Kwipakira bisanzwe: 2-8 interuro.
• Ibikoresho bya Molybdenum (urugero, MoO₃, Amonium Molybdate):
  • Kurwanya umwotsi ukomeye hamwe na flame retardant synergy. Kwipakira bisanzwe: 2-5 interuro.
• Nano yuzuza (urugero, Nanoclay):
  • Imizigo mike (3-8 interuro) itezimbere umuriro (gushiraho char, kugabanya ubushyuhe bwo kurekura) hamwe nubukanishi. Gutatana ni ngombwa.

3. Kurwanya umwotsi

PVC itanga umwotsi mwinshi mugihe cyo gutwikwa. Halogen idafite formulaire isaba guhagarika umwotsi. Zinc borate, zinc stannate, hamwe na molybdenum ibice ni amahitamo meza.

Icyifuzo cya Halogen-Yubusa Flame Retardant (Ukurikije umwimerere wabakiriya)

Intego: Kugera kuri UL94 V-0 (1,6 mm cyangwa umubyimba) mugihe ukomeza ubworoherane, gutunganya, nibintu byingenzi.

Ibitekerezo:

• Imiterere y'umwimerere:
  • DOP: interuro 50-70 (plastike).
  • ST: Birashoboka aside aside (lubricant).
  • HICOAT-410: Ca / Zn stabilisateur.
  • BZ-500: Birashoboka ko amavuta yo kwisiga / gutunganya (kwemeza).
  • EPOXY: Amavuta ya soya ya Epoxiside (co-stabilisateur / plastike).
  • Antimony: Sb₂O₃ (gukurwaho).

1. Basabwe gushiraho uburyo bwo gukora (kuri 100 interuro ya PVC)

2. Gutanga urugero (Bisaba Optimisation)

Intambwe Zishyirwa mu bikorwa

1. Emeza Ibikoresho Byibanze:
   • Sobanura ibiranga imiti yaBZ-500naST(baza inama zitanga amakuru).
   • Kugenzura imitwaro nyayo yaDOP,EPOXY, naHICOAT-410.
   • Sobanura ibyifuzo byabakiriya: Target flame retardancy (eg, uburebure bwa UL94), ubworoherane (ubukana), gusaba (imodoka, ibikoresho byo mu nzu, imifuka?), Ibikenewe bidasanzwe (kurwanya ubukonje, guhagarara kwa UV, kurwanya abrasion?), Imipaka ntarengwa.
2. Hitamo amanota yihariye ya Flame Retardant:
   • Saba halogen-idafite flame retardant ingero zagenewe uruhu rwa PVC kubatanga isoko.
   • Shyira imbere ubuvuzi bwa ATH / MDH kugirango ukwirakwizwe neza.
   • Kuri APP, koresha amanota menshi-yihanganira amanota.
   • Kuri fosifate ester, hitamo RDP / BDP kuruta TCPP kugirango wimuke.
3. Kwipimisha Ibipimo & Gukwirakwiza:
   • Tegura uduce duto hamwe nuburemere butandukanye (urugero, hindura MDH / APP / ZB / ZS).
   • Kuvanga: Koresha ivanga ryihuta (urugero, Henschel) kugirango utatanye. Ongeramo amazi (plasitike, stabilisateur) ubanza, hanyuma ifu.
   • Gutunganya Ibigeragezo: Ikizamini kubikoresho bitanga umusaruro (urugero, kuvanga Banbury + calendering). Kurikirana igihe cyo guhindagurika, gushonga ubwiza, torque, ubwiza bwubuso.
   • Kwipimisha Imikorere:
     • Kubuza umuriro: UL94, LOI.
     • Ibikoresho bya mashini: Gukomera (Inkombe A), imbaraga zingana, kuramba.
     • Kwiyoroshya / ukuboko kumva: Ibizamini + bikomeye.
     • Ubushyuhe buke bwo guhinduka: Ikizamini gikonje.
     • Ubushyuhe bwumuriro: Ikizamini gitukura cya congo.
     • Kugaragara: Ibara, indabyo, gushushanya.
     • (Bihitamo) Ubucucike bwumwotsi: NBS icyumba cyumwotsi.
4. Gukemura ibibazo & Kuringaniza:

5. Umuderevu & Umusaruro: Nyuma yo gukora laboratoire, kora ibigeragezo kugirango ugenzure ituze, ihamye, nigiciro. Gupima gusa nyuma yo kwemezwa.

Umwanzuro

Guhindura kuva muri antimoni bishingiye kuri halogen idafite flame-retardant uruhu rwa PVC birashoboka ariko bisaba iterambere ryuzuye. Uburyo bwibanze bukomatanya hydroxide yicyuma (byaba byiza bivuwe na MDH), fosifore-azote ikomatanya (APP cyangwa ADP), hamwe nogukumira imyotsi myinshi (zinc borate, zinc stannate). Icyarimwe, guhitamo plasitike, stabilisateur, amavuta, nibikoresho bifasha gutunganya ni ngombwa.

Urufunguzo rwo gutsinda:

1. Sobanura intego n'imbogamizi zisobanutse (flame retardancy, imitungo, igiciro).
2. Hitamo ibimenyetso bya halogen-bidafite flame retardants (hejuru-yuzuye yuzuza, hejuru-temp APP).
3. Kora ibizamini bya laboratoire (flame retardancy, imitungo, gutunganya).
4. Menya neza kuvanga kimwe no guhuza inzira.
