Ewezuga ụdị rọba sịntetịt ole na ole, ọtụtụ ngwaahịa roba sịntetik , dị ka eke roba , bụ ihe na-ere ọkụ ma ọ bụ ọkụ . Na ụlọ ọrụ ndị dị ka ume ọhụrụ, batrị usoro , na ngwá electronic , A na-etinye ihe ndị na-egbochi ọkụ ọkụ dị elu na ihe ndị dị na roba, karịsịa maka ngwaahịa ndị dị ka Mpempe batrị na Halogen-Ọkụ na-adịghị na-egbochi mmaja.
Ka ọ dị ugbu a, isi ụzọ teknụzụ maka imeziwanye ihe ire ọkụ nke ngwaahịa roba gụnyere:
Na-agbakwụnye ọkụ retardants ma ọ bụ ihe ndochi ire ọkụ
Ngbanwe mgbanwe ya na ihe na-egbochi ire ọkụ
Na-ewebata otu ọrụ na-egbochi ire ọkụ n'oge polymerization
Na-abawanye crosslink njupụta nke ngwaahịa roba
Ndị na-esonụ ngalaba na-enye nkenke nkenke na nkọwa nke teknụzụ na-egbochi ọkụ roba.
1. Teknụzụ na-egbochi ire ọkụ maka roba hydrocarbon
1.1 Njirimara nke Hydrocarbon Rubbers
Hydrocarbon roba tumadi gụnyere:
NR (Roba eke)
SBR (Styrene-Butadiene rọba)
BR (Butadiene rọba)
IIR (Butyl rọba)
EPR/EPDM (Ethylene Propylene Rubber)
Agbanyeghị NBR (Nitrile rubber) abụghị ahụkarị hydrocarbon roba, ya ụzọ ọgwụgwọ ire ọkụ yiri nke a, a na-ekwurịtakwa ya ọnụ na ngwa injinịa.
Isi njirimara nke hydrocarbon rubbers gụnyere:
Ndepụta Oxygen na-egbochi (LOI): ihe ruru. 19–21
Okpomọkụ ire ere: 200-500°C
Ọkụ ọkụ na-adịghị mma na nguzogide okpomọkụ
Ọgbọ nke nnukwu ichekwa gas na-ere ọkụ n'oge combustion
Ya mere, mgbe eji na Mpempe batrị, ulo oru damping pads , ma ọ bụ ihe ndị dịpụrụ adịpụ nke ọma jijiji n'ozuzu , Mgbanwe ire ọkụ dị mkpa.
1.2 Ụzọ na-egbochi ire ọkụ na-emekarị maka rubbers hydrocarbon
(1) Na-ejikọta ya na polymer na-egbochi ire ọkụ
Site na ịgwakọta rọba hydrocarbon na polymer na-egbochi ire ọkụ dị ka:
Polyvinyl chloride (PVC)
Polyethylene Chlorinated (CPE)
Polyethylene chlorosulfonated (CSM)
Ethylene-Vinyl Acetate (EVA)
enwere ike imeziwanye ọkụ ọkụ ruo n'ókè ụfọdụ. N'oge ngwakọta, a ghaghị ịkwụ ụgwọ nlebara anya pụrụ iche:
Ndakọrịta ihe
Nhazi usoro ihe jikọrọ ọnụ
A na-ejikarị usoro a eme ihe maka Pads batrị arụrụ arụ ma ọ bụ ihe ndị na-eme ka mmiri na-ekpo ọkụ na-adịghị elu.
(2) Mgbakwunye nke ndị na-agbapụta ọkụ (ụzọ mbụ)
Ihe mgbakwunye nke ọkụ retardants bụ ụzọ kachasị mkpa maka ịkwalite ire ọkụ na rọba hydrocarbon ma nwee ike imeziwanye ya site na. synergistic usoro.
Organic halogen dabere ire retardants (ihe ngwọta ọdịnala):
Ihe mgbapụta Hexachlorocyclopentadiene
Decabromodiphenyl ether
Paraffin chlorinated
Inorganic synergistic ire ọkụ retardants:
Antimony trioxide (Sb₂O₃) (nke a na-ejikarị)
Zinc borate
Aluminom hydroxide
Ammonium chloride
⚠ Ihe ndetu dị mkpa:
Ihe mgbochi ọkụ dabere na halogen agaghị enwe halogen n'efu , ma ọ bụghị ha nwere ike:
Corrode nhazi akụrụngwa na ebu
Belata ọrụ mkpuchi ọkụ eletrik
Na-emetụta iguzogide ịka nká nke ọma
N'ime ume ọhụrụ na ụlọ ọrụ eletrọnịkị, Halogen-Ọkụ na-adịghị na-egbochi mmaja aghọwo isi ihe, na-eduga na mmasị siri ike maka Sistemụ nchekwa ọkụ na-enweghị halogen.
(3) Mgbakwunye nke ọkụ na-eme ka ọkụ na-eme ka ihe ndị na-adịghị na ya pụta
Ihe ndochi a na-ejikarị gụnyere:
Calcium carbonate
Kaolin ụrọ
Talc
Silica gbara mmiri
Aluminom hydroxide
Usoro a na-eme ka ire ọkụ na-adịgide adịgide site na:
Na-ebelata oke nke combustible organic ihe
Iji ihe mmetụta decomposition endothermic nke fillers
Ọmụmaatụ:
Calcium carbonate na aluminum hydroxide banye nnukwu okpomọkụ n'oge ire ere
Otú ọ dị, a ghaghị itinye nlebara anya n'eziokwu ahụ:
Ịkwanye ihe ndochi dị ukwuu na-ebelata n'ibu Njirimara
Ọ bụghị adabara elu-elasticity ma ọ bụ ihe ndị dịpụrụ adịpụ vibration dị elu
(4) Na-abawanye njupụta Rubber Crosslink
Nnyocha egosiwo na:
Njupụta crosslink dị elu → Ndekọ oxygen dị elu → Ọganihu ire ọkụ
Usoro a nwere ike jikọta ya na mmụba na okpomọkụ ire ere.
E tinyela usoro a nke ọma na Sistemụ rọba EPDM na adabara:
A na-eji paịlị batrị eme ihe na gburugburu okpomọkụ ruo ọkara ruo elu
Ihe arụrụ arụ nke ire ọkụ na-egbochi ịma jijiji damping akụrụngwa rọba
2. Àgwà ndị na-egbochi ọkụ nke rubbers halogenated
Rubbers halogenated nwere ihe halogen n'onwe ya ma na-egosipụtakarị:
Ndekọ ikuku oxygen: 28-45
FPM (Fluororubber) ikuku oxygen karịrị 65
Ọdịnaya halogen dị elu → mma ire ere retardancy
Omume igbu onwe ya mgbe ewepụrụ ire ọkụ
N'ihi ya, ọgwụgwọ na-egbochi ire ọkụ nke rubbers halogenated dị mfe, na-achọkarị naanị obere nkwado na ọkụ retardants.
⚠ Otú ọ dị, n'ihi na ụkpụrụ gburugburu ebe obibi (dị ka RoHS na rute ) na ọnọdụ na ụlọ ọrụ ike ọhụrụ, ngwọta na-enweghị halogen na-enwewanye mmasị. Nke a bụ isi ihe kpatara nnabata zuru ebe niile Halogen-Ọkụ na-adịghị na-egbochi mmaja.
3. Teknụzụ na-egbochi ọkụ maka Heterochain Rubbers
Kacha nnọchiteanya heterochain roba bụ:
Dimethyl silicone rọba (VMQ)
Njiri mara ya gụnyere:
Oxygen index nke ihe dịka 25
Okpomọkụ ire ere ruo 400-600 Celsius
Nkwụsi ike dị elu dị oke mma
Usoro na-egbochi ire ọkụ nke rọba silicone na-agụnyekarị:
Na-abawanye thermal decomposition okpomọkụ
Na-abawanye ego nke cha cha fọdụrụ mgbe ire ere
Na-ebelata ọnụ ọgụgụ ọgbọ nke gas na-ere ọkụ
N'ihi ya, roba silicone a na-ejikarị eme ihe na:
Mpempe batrị dị elu
Ihe ndị na-egbochi ọkụ na-egbochi halogen dị elu
Ihe nchekwa nchekwa maka ngwa eletrọnịkị na akụrụngwa ume ọhụrụ
Mmechi
The ire-retardant imewe nke ngwaahịa rọba a ga-atụle n'ụzọ zuru ezu dabere na ụdị roba, ngwa gburugburu , na usoro iwu chọrọ.
Maka ngwa dị ka:
Mpempe batrị
Halogen-Ọkụ na-adịghị na-egbochi mmaja
a na-atụ aro ka ibute ụzọ:
Sistemụ nchekwa ọkụ na-enweghị halogen
Ngosipụta njupụta crosslink kwesịrị ekwesị
Ngwọta ziri ezi n'etiti ndị na-eku ọkụ na-ere ọkụ na arụ ọrụ igwe
Ewezuga ụdị rọba sịntetịt ole na ole, ọtụtụ ngwaahịa roba sịntetik , dị ka eke roba , bụ ihe na-ere ọkụ ma ọ bụ ọkụ.
