Matakan Gudanarwa:
- Premix nailan guduro, harshen wuta retardant, mai mai, da kuma antioxidant iri ɗaya.
- Narke-haɗe ta amfani da twin-screw extruder da pelletize.
- Sarrafa zafin jiki na extrusion a 240-280 ° C (daidaita bisa nau'in nailan).
Halaye:
- Amfani: Abokan muhalli, babu hayaki mai guba, mai bin ka'idoji.
- Rashin amfani: Ƙarƙashin ƙarancin harshen wuta, ƙimar ƙari mafi girma, tasiri mai tasiri akan kaddarorin inji.
4. Mahimman ra'ayi a cikin Ƙirar Ƙira
(1) Zaɓin Ƙunƙarar Wuta
- Halogenated harshen wuta retardants: Babban inganci amma yana haifar da haɗarin muhalli da lafiya.
- Halogen-free harshen retardants: Eco-friendly amma yana buƙatar adadi mai yawa kuma yana iya rinjayar aikin kayan aiki.
(2) Amfani da masu haɗin gwiwa
- Antimony trioxide: Yana aiki tare tare da halogenated harshen retardants don haɓaka jinkirin harshen.
- Phosphorus-nitrogen aiki tare: A cikin tsarin da ba shi da halogen, masu riƙe harshen wuta na tushen phosphorus da nitrogen na iya yin aiki tare don haɓaka aiki.
(3) Watsewa da Tsari
- Masu watsewa: Tabbatar da rarrabuwar kawuna na magudanar wuta don gujewa babban taro na gida.
- Man shafawa: Inganta sarrafa ruwa da rage lalacewa na kayan aiki.
(4)Antioxidants
Hana lalata kayan aiki yayin sarrafawa da haɓaka daidaiton samfur.
5. Aikace-aikace na yau da kullun
- Kayan lantarki: Abubuwan da ke hana harshen wuta kamar masu haɗawa, masu sauyawa, da kwasfa.
- Motoci: phr mai hana wuta kamar murfin injin, kayan aikin waya, da abubuwan ciki.
- Yadi: Filaye da yadudduka masu hana harshen wuta.
6. Shawarwari ingantawa Formulation
(1) Haɓaka Ƙarfafa Ƙwararrun Ƙwararru
- Haɗewar harshen wuta: Halogen-antimony ko phosphorus-nitrogen synergies don inganta aikin.
- Nano harshen wuta retardants: Misali, nano magnesium hydroxide ko nano lãka, don inganta yadda ya dace da kuma rage adadin ƙari.
(2) Inganta Kayayyakin Injini
- Masu tauri: Misali, POE ko EPDM, don haɓaka ƙarfin abu da juriya mai tasiri.
- Ƙarfafa filaye: Misali, gilashin fiber, don inganta ƙarfi da rigidity.
(3) Rage Kuɗi
- Haɓaka ma'aunin jinkirin harshen wuta: Rage amfani yayin saduwa da buƙatun jinkirin harshen.
- Zaɓi kayan aiki masu tsada: Misali, na gida ko gaurayewar harshen wuta.
7. Bukatun Muhalli da Ka'idoji
- Halogenated harshen wuta retardants: Ƙuntatawa ta RoHS, REACH, da sauransu, yana buƙatar amfani da hankali.
- Halogen-free harshen retardants: Mai yarda da ƙa'idodi, wakiltar abubuwan da ke gaba.
Zane-zanen ƙirar nailan mai ɗaukar harshen wuta yakamata yayi la'akari da takamaiman yanayin aikace-aikacen da buƙatun ƙa'ida lokacin zabar halogenated ko mara-halogin harshen wuta. Halogenated harshen retardants suna ba da ingantaccen inganci amma suna haifar da haɗarin muhalli, yayin da hanyoyin da ba su da halogen suna da aminci ga yanayin yanayi amma suna buƙatar ƙarin ƙari. Ta hanyar inganta ƙira da matakai, ingantaccen, abokantaka da muhalli, da kayan nailan masu kashe wuta mai tsada za a iya haɓaka don biyan buƙatun na'urorin lantarki, motoci, masaku, da sauran masana'antu.
