3. Tsarin Nailan Mai Hana Wuta Ba Tare Da Halogen Ba
Masu hana harshen wuta marasa halogen (misali, masu tushen phosphorus, masu tushen nitrogen, ko kuma masu inorganic hydroxides) suna aiki ta hanyar halayen endothermic ko samuwar Layer mai kariya, suna ba da ingantaccen aikin muhalli.

- Hydroxide mara tsari: 20-30 phr (misali, magnesium hydroxide ko aluminum hydroxide)
- Man shafawa: 1-2 phr (misali, sitaci na zinc)
- Maganin hana tsufa: 0.5–1 phr (misali, 1010 ko 168)
Matakan Sarrafawa:
- An haɗa resin nailan, mai hana harshen wuta, mai shafawa, da kuma maganin antioxidant a lokaci guda.
- Narkewa ta amfani da na'urar fitar da sukurori biyu da kuma pelletize.
- Sarrafa zafin fitarwa a 240–280°C (daidaita bisa ga nau'in nailan).
Halaye:
- Fa'idodi: Yana da kyau ga muhalli, babu hayakin iskar gas mai guba, kuma yana bin ƙa'idodi.
- Rashin amfani: Ƙarancin ingancin hana harshen wuta, ƙarin adadin ƙari, da yuwuwar tasiri ga halayen injiniya.
4. Muhimman Abubuwan Da Ake La'akari Da Su A Tsarin Tsarin
(1) Zaɓin Mai Hana Wuta
- Masu hana harshen wuta ta halogenated: Ingantaccen aiki amma yana haifar da haɗarin muhalli da lafiya.
- Masu hana harshen wuta marasa halogen: Yana da kyau ga muhalli amma yana buƙatar adadi mai yawa kuma yana iya shafar aikin kayan aiki.
(2) Amfani da Masu Haɗa Jiki
- Antimony trioxide: Yana aiki tare da masu hana harshen wuta na halogen don haɓaka jinkirin harshen wuta.
- Haɗin kai tsakanin phosphorus da nitrogen: A cikin tsarin da ba shi da halogen, masu hana harshen wuta na phosphorus da nitrogen na iya haɗa kai don inganta aiki.
(3) Watsawa da Sauƙin Sarrafawa
- Masu rarrabawa: Tabbatar da cewa an rarraba na'urorin hana harshen wuta iri ɗaya domin guje wa yawan taruwar da ake samu a wurare daban-daban.
- Man shafawa: Inganta sauƙin sarrafawa da rage lalacewar kayan aiki.
(4) Magungunan hana tsufa
Hana lalacewar kayan aiki yayin sarrafawa da kuma inganta daidaiton samfurin.
5. Aikace-aikacen da Aka saba
- Lantarki: Abubuwan da ke hana harshen wuta kamar masu haɗawa, maɓallan wuta, da soket.
- Motoci: PHR mai hana harshen wuta kamar murfin injin, igiyoyin wayoyi, da kayan cikin gida.
- Yadi: Zaruruwa da yadi masu hana harshen wuta.
6. Shawarwari Kan Inganta Tsarin
(1) Inganta Ingancin hana harshen wuta
- Haɗawa mai hana harshen wuta: Haɗin halogen-antimony ko phosphorus-nitrogen don inganta aiki.
- Nano harshen wuta retardantsMisali, nano magnesium hydroxide ko nano lãka, don haɓaka inganci da rage adadin ƙari.
(2) Inganta Halayen Inji
- Masu TauriMisali, POE ko EPDM, don haɓaka ƙarfin abu da juriyar tasiri.
- Masu ƙara ƙarfi: Misali, zare na gilashi, don inganta ƙarfi da tauri.
(3) Rage Farashi
- Inganta rabon hana harshen wuta: Rage amfani yayin da ake biyan buƙatun hana harshen wuta.
- Zaɓi kayan da ba su da tsada sosai: Misali, na'urorin hana harshen wuta na gida ko na gauraye.
7. Bukatun Muhalli da Dokokin
- Masu hana harshen wuta ta halogenated: An takaita shi ta hanyar RoHS, REACH, da sauransu, wanda ke buƙatar amfani da shi a hankali.
- Masu hana harshen wuta marasa halogen: Yana bin ƙa'idodi, yana wakiltar yanayin da zai faru nan gaba.
Tsarin tsarin hana harshen wuta na nailan ya kamata ya yi la'akari da takamaiman yanayin aikace-aikace da buƙatun ƙa'idoji yayin zaɓar masu hana harshen wuta na halogen ko halogen. Masu hana harshen wuta na halogen suna ba da inganci mai yawa amma suna haifar da haɗarin muhalli, yayin da madadin da ba su da halogen suna da kyau ga muhalli amma suna buƙatar ƙarin ƙari mai yawa. Ta hanyar inganta tsari da tsari, ana iya haɓaka kayan nailan masu inganci, masu aminci ga muhalli, kuma masu araha don biyan buƙatun kayan lantarki, motoci, yadi, da sauran masana'antu.
