Tlhahiso ea Litšupiso ea PP V2 Flame Retardant Masterbatch
Bakeng sa ho fihlella ho thibela malakabe ha UL94 V2 ho PP (polypropylene) masterbatches, ho hlokahala motsoako o kopanetsoeng oa ho thibela malakabe ha ho ntse ho bolokoa ts'ebetso ea ts'ebetso le thepa ea mechini. Ka tlase ke khothaletso e ntlafalitsoeng ea sebopeho ka litlhaloso:
I. Khothaletso ea Sebopeho sa Motheo
Sebopeho se Sitisang Mollo:
| Karolo | Ho kenya (boima%) | Tlhaloso ea Mosebetsi |
| Resin ea PP | 50-60% | Resin ea mojari (khothaletsa sehlopha sa index ea phallo e qhibilihang e phahameng, mohlala, MFI 20-30 g/10min) |
| Hypophosphite ea Aluminium | 15-20% | Mohloli oa asiti, o khothalletsa ho thehoa ha char, botsitso bo botle ba mocheso bakeng sa ts'ebetso ea PP |
| Borate ea Zinki | 5-8% | Se thibelang malakabe se sebetsang hammoho, se thibela mosi le ho eketsa ho thibela malakabe ka mokhoa oa khase |
| Aluminium Hydroxide e Fetotsoeng ka Holimo | 10-15% | Ho bola ha endothermic, ho fokotsa mocheso oa ho tuka (phekolo ea bokaholimo, mohlala, sesebelisoa sa ho kopanya sa silane, se khothaletsoa) |
| Dipentaerythritol (Di-PE) | 5-8% | Mohloli oa khabone, o sebelisana le mohloli oa asiti ho theha char ea intumescent |
| Melamine Polyphosphate (MPP) | 3-5% | Mohloli oa khase (tlatsetso e khothaletsoang), o ntša likhase tse sa sebetseng ho eketsa tlhahiso ea matla |
| Moemeli oa ho Thibela ho Rotha (PTFE) | 0.3-0.5% | E fokotsa ho rotha ha metsi ho qhibilihisang (ha ho hlokahale bakeng sa V2, kaha ho rotha hoa lumelloa) |
| Antioxidant (1010/168) | 0.3-0.5% | E thibela ho senyeha ha oxidative ea mocheso nakong ea ts'ebetso |
| Setlolo (Sinki Stearate) | 0.5-1% | E ntlafatsa ho phalla ha ts'ebetso le ho hasana |
| Mojari oa 'Mala le Pigment | Jwalo ka ha ho hlokahala | Khetha mebala e thibelang mocheso o phahameng ho qoba ho arabela ka lintho tse thibelang malakabe |
II. Lintlha tsa Bohlokoa tsa Ntlafatso
- Sistimi e Sireletsang Mollo e Kopanetsoeng
- Intumescent Flame Retardant (IFR):Aluminium hypophosphite (mohloli oa asiti) + Di-PE (mohloli oa khabone) + MPP (mohloli oa khase) li theha sistimi ea IFR, e etsang lera la char le sireletsang mocheso ho thibela mocheso le oksijene.
- Tšebelisano-'moho ea Zinc Borate:E arabela le aluminium hypophosphite ho etsa lera le sireletsang le kang khalase, e eketsang ho tiea ha lelakabe la kgase.
- Aluminium Hydroxide e Fetotsoeng:Kalafo ea bokaholimo e fokotsa ho lokolloa ha mongobo nakong ea ts'ebetso ha ka nako e ts'oanang e fana ka ho bola ha endothermic ho fokotsa mocheso oa ho tuka.
- Tekanyo ea Ts'ebetso le Tshebetso
- Kakaretso ea ho jara matla a thibelang malakabe e lokela ho laoloa ho35-45%ho qoba tahlehelo e kholo ea thepa ea mechini.
- SebelisaResin ea PP e nang le MFI e phahameng (mohlala, PPH-Y40)ho ntlafatsa ho hasana ha masterbatch le ho fokotsa ho teteana.
- Litlhahiso tsa Teko le Netefatso
- Teko ea ho Chesa ka ho Otloloha ea UL94:Netefatsa hore malakabe aa itima kahareMetsotsoana e 60kamora ho hotetsa habeli.
- Teko ea Mekaniki:Tsepamisa maikutlo ho matla a ho tsitlella (≥20 MPa) le matla a tshusumetso (≥4 kJ/m²).
- Ho Tsitsisa Thermal (TGA):Netefatsa hore mocheso oa ho bola ha malakabe o thibelang malakabe o tsamaellana le sebaka sa ts'ebetso ea PP (180–220°C).
III. Liphetoho tse sa khetheheng
- Bakeng sa ho Thibela ho Lakatseha ho Hoholo ha Mollo (mohlala, V0):
- Eketsa hypophosphite ea aluminium ho25%, eketsaSilicone ea 2%(ho thibela mosi), le ho phahamisa PTFE ho0.8%.
- Likopo tse Bontšang Litšenyehelo:
- Fokotsa diteng tsa MPP mme o eketse aluminium hydroxide ka tekanyo e itekanetseng (netefatsa botsitso ba ts'ebetso).
IV. Lintlha tsa bohlokoa tsa ho nahana
- Tlhahiso ea Masterbatch:Kopanya lintho tse thibelang malakabe esale pele le resin e tsamaisang;ho ntša li-screw tse peli (180–210°C)ho kgothaletswa.
- Ho omisa Aluminium Hydroxide:Omisa ho110°C ka lihora tse 4ho thibela lipululana nakong ea ts'ebetso.
- Di-PE/Aluminium Hypophosphite Ratio:Hloekisa1:2 ho isa ho 1:3bakeng sa katleho e ntle ea ho theha char.
Ka mokhoa ona o ntlafalitsoeng oa ho etsa le ho sebetsana le oona,Ho lieha ha lelakabe la UL94 V2e ka finyelloa ka ho tsitsa ha ho ntse ho bolokwa tshebetso ya ho sebetsana le botsitso ba mmala. Liteko tse nyane di kgothaletswa bakeng sa ho lokisa ho latela diphetho tsa diteko.
