Polypropylene (PP) Flame Retardant Masterbatch dabara dabara

Polypropylene (PP) Flame Retardant Masterbatch wani babban taro ne na cakuda wuta da guduro mai ɗaukar nauyi, wanda ake amfani da shi don sauƙaƙa gyare-gyaren harshen wuta na kayan PP. A ƙasa akwai cikakken tsari na PP harshen wuta retardant masterbatch tsari da bayani:

I. Basic Haɗin gwiwar PP Flame Retardant Masterbatch

• Guduro mai ɗaukar kaya: Yawanci PP, yana tabbatar da dacewa mai kyau tare da kayan tushe.
• Mai hana wuta: Halogenated ko halogen-free, zaba bisa buƙatun.
• Synergist: Yana haɓaka jinkirin wuta (misali, antimony trioxide).
• Watsewa: Yana inganta tarwatsa masu kare wuta.
• Mai mai: Yana inganta sarrafa ruwa.
• Stabilizer: Yana hana lalacewa yayin sarrafawa.

II. Halogenated Flame Retardant PP Masterbatch Formulation

Halogenated harshen retardants (misali, brominated) haɗe da antimony trioxide yana ba da ingantaccen aiki.

Misali Formulation:

• Guduro mai ɗaukar nauyi (PP): 40-50%
• Brominated harshen wuta retardant (misali, decabromodiphenyl ether ko brominated polystyrene): 30-40%
• Antimony trioxide (synergist): 5-10%
• Mai watsawa (misali, polyethylene kakin zuma): 2-3%
• Man shafawa (misali, calcium stearate): 1-2%
• Antioxidant (misali, 1010 ko 168): 0.5-1%

Matakan sarrafawa:

1. Pre-hada duk abubuwan da aka gyara daidai.
2. Narke-haɗe ta amfani da twin-screw extruder da pelletize.
3. Sarrafa zafin jiki na extrusion a 180-220 ° C.

Halaye:

• Babban jinkirin harshen wuta tare da ƙaramar ƙarawa kaɗan.
• Zai iya sakin iskar gas mai guba yayin konewa.
• Ya dace da aikace-aikace tare da ƙananan bukatun muhalli.

III. Halogen-Free Flame Retardant PP Masterbatch Formulation

Abubuwan da ba su da halogen (misali, phosphorus-, tushen nitrogen, ko inorganic hydroxides) suna da aminci ga muhalli amma suna buƙatar ƙarin lodi.

Misali Formulation:

• Guduro mai ɗaukar nauyi (PP): 30-40%
• Retardant na tushen phosphorus (misali, ammonium polyphosphate APP ko jan phosphorus): 20-30%
• Tushen Nitrogen Retardant (misali, melamine cyanurate MCA): 10-15%
• Magnesium hydroxide ko aluminum hydroxide: 20-30%
• Mai watsawa (misali, polyethylene kakin zuma): 2-3%
• Man shafawa (misali, zinc stearate): 1-2%
• Antioxidant (misali, 1010 ko 168): 0.5-1%

Matakan sarrafawa:

1. Pre-hada duk abubuwan da aka gyara daidai.
2. Narke-haɗe ta amfani da twin-screw extruder da pelletize.
3. Sarrafa extrusion zafin jiki a 180-210 ° C.

Halaye:

• Eco-friendly, babu gas mai guba a lokacin konewa.
• Maɗaukakin ƙara lodi zai iya lalata kaddarorin inji.
• Ya dace da aikace-aikace tare da ƙaƙƙarfan ƙa'idodin muhalli.

IV. Mahimmin La'akari a cikin Ƙirar Ƙira

• Zaɓin riƙe wuta: Zaɓi halogenated ko halogen-free dangane da juriya na harshen wuta da ake buƙata da ƙa'idodin muhalli.
• Daidaita guduro mai ɗauka: Dole ne ya dace da tushen PP don hana lalata.
• Watsewa: Masu rarrabawa da man shafawa suna tabbatar da rarraba iri ɗaya na retardants.
• Tsarin zafin jiki: Ka guji zafi mai yawa don hana ruɓewa.
• Kayan aikin injiniya: High ƙari loadings na iya rage aiki; yi la'akari da abubuwan ƙarfafawa (misali, POE ko EPDM).

V. Aikace-aikace na yau da kullun

• Halogenated masterbatch: Gidajen lantarki, wayoyi / igiyoyi.
• Halogen-free masterbatch: Kayan ciki na mota, kayan gini, kayan wasan yara.

VI. Shawarwari ingantawa

• Haɓaka jinkirin harshen wuta: Haɗa magudanar ruwa da yawa (misali, haɗin gwiwar phosphorus-nitrogen).
• Inganta kayan aikin injiniya: Ƙara masu ƙarfi (misali, POE/EPDM).
• Rage farashi: Haɓaka ma'auni na retardant kuma zaɓi kayan aiki masu tsada.

Ta hanyar ƙira ta hankali da ƙirar sarrafawa, PP flame retardant masterbatches na iya biyan buƙatun aikace-aikace iri-iri.
Saboda ƙa'idodin muhalli da ƙarancin wadatar kayan aikin antimony trioxide, ƙarin adadin abokan ciniki suna ɗaukar abubuwan da ba su da halogen-free phosphorus-nitrogen flame retardatches don PP masterbatches. Misali,TF-241ana iya amfani da su kai tsaye zuwa samfuran PP da masterbatches, samun nasarar ƙirƙirar char-forming da tasirin intumescent ba tare da ƙarin ƙari ba. Don haɓaka kaddarorin injiniyoyi, ana ba da shawarar adadin masu amfani da robobi da masu haɗa haɗin gwiwa.
