I-polyphenyne sulfide sulfide odumileyo kwiplasitiki yobunjineli

Kwizixhobo ezininzi ezithandwayo zobunjineli beeplanga zobunjineli, impahla enye eyaziwa ngokubanzi yiPolyphenyane Sulfiide (PPS).

Ngaba ubusazi ukuba iiplasitiki zobunjineli ziphantsi koxinzelelo lwexesha elide lokunxibelelana kunye nendawo yemichiza kunye nendawo yokuhlala? Iiplasitiki zobunjineli kufuneka zikwazi ukumelana noxinzelelo loomatshini ixesha elide, kodwa kufuneka zikwazi ukumelana nendawo yemichiza kunye nendawo yomzimba, kunye ne-polyphenyane sulfide aziqhelekanga kakhulu kule meko.

Ineepropathi ezingcono zoomatshini, iipropathi zombane, ukungavisisaniswa kwamachiza, ukuxhathisa ubushushu, ukuxhathisa ubushushu, ukunganyangeki kwe-abrasion kunye nozinzo oluneplanga ngokubanzi. Isitshixo kukuba ilula kunentsimbi, kulula ukuyilolonga, ukusetyenziswa kwamandla nako kuncinci, kusetyenziswa ngokubanzi kwi-elektroniki, ukwakhiwa, oomatshini, i-aerospace kunye nezinye iinkalo ezininzi.

Ukuxhathisa ubushushu kungcono ngakumbi, indawo yokunyibilika inokufikelela kwi-275-291 ℃, iqondo lokushisa i-Fibt le-135 ℃, i-fiber fiber eqingqiweyo ukuya kwi-260 ℃. Emoyeni kunye ne-nitrogen, iqondo lokushisa eliqaqambileyo elinama-400 ° C, i-700 ° C kwi-Air Areations, i-1000 ° C I-CATE ye-InErt inokuthi igcine i-40% yobunzima. Ubushushu bexesha elide lokusetyenziswa kwexesha le-200 - i-240 ℃, igesi yomqobo wobuqhetseba kunye nokusetyenziswa kwexesha elide ukusetyenziswa kozinzo lobuchwephesha kunazo zonke iiplasitiki zobunjineli.

Iipropathi zoomatshini, kukungqongqo kakuhle, kodwa thambekele ekuxhaseni ukugxininisa kwi-Bengne, ipetroli kunye nezinye izinyibilikisi zendalo. Nangona kunjalo, emva kongeza i-fiber yeglasi okanye ezinye izinto zokwenza izinto eziguqulweyo, amandla empembelelo, ukumelana nobushushu kunye nezinye iipropathi ezixhaphakileyo, izixhobo zekhemikhali, izixhobo zokukhanya kunye namanye amalungu.

Ngenxa yendlela yayo yokuzihlaziya kunye nomxholo wesalfure, i-polyphenylene sulfide ingayidlulisa uvavanyo lokuhlawula i-UL-94 v0 ngobungqingqwa be-0.8mm, iplasitiki esebenzayo, kwaye ke ibalulekile kwicandelo lokungakhathali kwe-radiation iimfuno. Ayisiyiyo kuphela, ukunganyangeki kwe-corosion yayo ibaluleke kakhulu, ukongeza kwi-oxiding acid, iphantse ixhathise uninzi lwe-acid, uzinzo lwekhemikhali kunye nemozulu kunye nokunganyangekala kwemitha kunye nokunganyangeka kwe-radication kunye nokunganyangeka kwe-radication kunye nokunganyangeka kwe-radis kunye nokunganyangeka kwe-radication kunye nokunganyangekala kwemitha kunye nokunganyangeka kwe-radication kunye nokunganyangekala kwemitha kunye nokunganyangeka kwe-radication kunye nokunganyangekala kwemitha kunye nokunganyangeka kwe-radication kunye nokunganyangekala kwemitha kunye nokunganyangeka kwe-radication.

Iipropathi zombane zilungele kakhulu, ubushushu obuphezulu kunye neemeko eziphakamileyo, ukutshintsha kwevolo kukuhlala zincinci, ukukhola kokuthintela amaqondo obushushu, kulungele iipropathi zombane zemveliso zifuna kakhulu .

Ukusebenza kwawo okusebenzayo kulungile, ukunyibilika okuphantsi, kulula ukunxibelelana nge-fiber emanzi kunye nokugcwalisa i-fiber, i-bonding ephezulu, i-aluminium, izixhobo ezingenasitayile kunye nezinye izinto. Uzinzo olubalaseleyo, amanzi aphantsi kunye ne-oyile, i-shrinking encinci ye-shrinking kunye ne-coanded yokwandiswa, uzinzo lwemveliso, kwindawo enomswakalo okanye imeko enomtsalane okanye ilungele ukubumba okuchanekileyo.

Kwaye ujonge izicelo zayo, ezijikelezwe kakhulu:

Kwintsimi yenxalenye yeolimotive, inokutshintsha inyibilikisi kunye ne-thermoset i-intermoset yenxalenye ye-injini, iinxalenye ze-injini, iinxalenye ze-Brake, iinxalenye, iinxalenye ezipholileyo, njalo njalo.

Kwindawo yokuhlala kunye nezixhobo ezichanileyo, ezinjengee-reters ezichazayo, izixhobo ezinxulumene namanzi, izixhobo ezichanileyo, izixhobo zePPE zithatha indawo yezixhobo zentsimbi kunye nokunganyangeki koxinzelelo, kunye nobunzima.

Kwintsimi yombane / ye-elektroniki, isetyenziswa kwiindawo zombane / ze-elektroniki ezinje ngezixhobo, kunye nokuxhathisa ubushushu bayo, nokuzinza ngokuchanekileyo, ukuzinza ngokuchanekileyo, kunye nokubuyisa okuphezulu kwelangatye.

Kwicandelo lecandelo lomatshini kunye nomzi mveliso weekhemikhali, idityaniswe ne-fiber yefibre, i-mineral filler okanye i-carbon fiber ukwenza izinto ezihlanganisiweyo, ezisetyenziselwa ukwenza izixhobo zendlela kunye nezixhobo zekhemikhali.

Kwicandelo leebhetri ze-lithium, ukumelana nobushushu, i-insultimes kunye neepropathi zombane zenza ukuba kube yi-hit enkulu.

Kwintsimi yokukhusela kwendalo, iimveliso ze-PPS zinemigangatho eyomeleleyo enokubakho kwirhasi kunye nonyango oluphezulu, ukuxhathisa kobushushu obuphezulu, ii-rosions kunye nemikhono yentsimbi, izityalo zokufudumeza kunye nezinye iindawo ezidlala indima ebalulekileyo.

Okulandelayo, masithelekise ipollfonlene sulfiide (PPS) ngenye iplastiki yobunjineli bentsebenzo ephezulu, i-Peek.

Ngokumalunga nokumelana nobushushu, i-Peek inobushushu benkonzo yexesha elide engama-260 ° C, engaphezulu kakhulu kune-PPS. Nangona kunjalo, i-polyphenylene sulfide inenzuzo ngokwexabiso.

Ngokuphathelele kwiipropathi zoomatshini, amandla kunye nobunzima be-peek ihlala ilunge ngakumbi kune-polyphenyane sulfide, nangona i-polyphenyane sulfide inokuguqulwa ukuze ikwazi ukujongana neemfuno ezininzi zesicelo.

Ngokwendlela yokusebenza yokusebenza, i-polyphenylene iulfide inomxholo ophantsi, i-slidisity engcono, kwaye ilula ukuyiqhubela phambili kunye nokubumba.

Ukusuka kwimbono yamaxabiso, i-PPS ngokubanzi ifikeleleka ngakumbi kune-peek, isenze yathandwa kakhulu kwizicelo ezinobuthathaka.

I-polyphenyne sulfiide kwaye i-Peek nganye inezibonelelo zawo, kwaye ukhetho lwesicelo oluthile luxhomekeke kwiimfuno ezithile zokusetyenziswa kunye nokuqwalaselwa kweendleko.

I-polyphenyne sulfide (PPS) yiplastiki yobunjineli bobuchwephesha egqwesileyo kwiindawo ezahlukeneyo. Njengezinto ezibunjiweyo, zinokutshintsha iinyithi kunye nee-resins zokunyanga ubushushu, zinobushushu obuqinisekileyo obuqhubekayo, ziphucula iimveliso, kwaye zinciphisa iindleko, kunye nokuzisa izibonelelo ezininzi kumashishini ahambelana nemizi mveliso.
