I-PPs yi-sulfur-equkethe i-thelymers evuthayo, i-PPS ye-PPS engaphezulu kwe-350 ℃ yokufumana inkampani ye-thertoves, i-PPS ye-piin piin i-hillip, i-PPS ye-United States ye-United States, i-Patent yelungelo elilodwa lomenzi wechiza, i Iinkampani zaseJapan zaqala ukukhula nokuvelisa. Emva kokuphelelwa kwelungelo elilodwa lomenzi wechiza, iinkampani zaseJapan nazo zaqala ukuqhuba nophuhliso kunye nemveliso. Amashishini aseJapan aqhelene ngokunyanzeleka kweJapan, imveliso yaseJapan ibinkulu kune-United States ngeli nqanaba lemveliso. Abanye abavelisi ikakhulu ikakhulu bagxile kwi-United States naseJapan, amazwe aseNtshona Yurophu ngoku akavelisi iPPS. Ngo-2000, ukuveliswa kwePPS kunokufikelela kwi-50 000t / a. Imfuno ye-PPS yeJapan ibalelwa kwi-33% yenkulu, iMantla Melika ibalwe i-32% yeYurophu ibalelwa kwi-19 yeepesenti ye-16%.
Okokuqala, iipropathi ezibonakalayo
1, Ukufakelwa kombane (ngakumbi i-insultured ye-Right) ilungele, imhlophe, i-Fightle, iwele emhlabeni kuphela, ukungcungcutheka kwamanzi, uzinzo lwamanzi, uzinzo lwamanzi, uzinzo lwamanzi, uzinzo lwamanzi. Iplastiki egqwesileyo, engagungqiyo.
2, Amandla gabalala, ubuqili bulungile, kodwa brigaletle, kulula ukuvelisa uxinzelelo, ukunganyamezelani. Ipetroli kunye nezinye izinyibilikisi zendalo. Ukusetyenziswa kwexesha elide kubushushu ukuya kuthi ga kwi-260 degrees, ngamanqanaba angama-400 omoya okanye initrogen ukuze uqiniseke uzinzo. Ngokungenisa i-fiber yeglasi okanye enye yezixhobo zokwenza izinto eziguquguqukayo, amandla empembelelo anokuphuculwa kakhulu, ukumelana nobushushu kunye nezinye iipropathi zoomatshini ziye zaphuculwa. Ukwenza iindawo ezinganyangekiyo zobushushu. Iinxalenye zokufakelwa kunye nezixhobo zekhemikhali. Izixhobo zamehlo kunye namanye amalungu.
Okwesibini, ukubumba ukusebenza
I-1. I-Amorphous Izixhobo, i-Absorped An
2, Ukuhamba phakathi kwe-ABS kunye ne-PC, ukuqina okukhawulezayo, i-shrinkige encinci, kulula ukubola, khetha uxinzelelo oluphezulu lwenaliti kunye nesantya esiphezulu. Iqondo lobushushu le-100-150 degrees. I-piestream taper kufuneka ibe nkulu, imbaleki ifanele ibe mfutshane. Ubungakanani besicelo ngokubanzi bunokusetyenziswa ekwenzeni umbhobho we-PPS, iphepha le-PPS kunye nezinye izinto, uninzi lwalusetyenziswa ekwakheni, ekhaya.
Iimpawu ze-PPs kunye nokusetyenziswa
I. IZIXHOBO
. ilangatye elihle, i-Inder ye-oxygen yayo ukuya kuthi ga kwi-44% okanye ngaphezulu; Xa kuthelekiswa nezinye iiplasitiki, yibhotsi ephakamileyo yedakisi kwi-plastics (i-PVC ecocekileyo yeoksijini ye-47%), i-PSF yi-30%, i-PSF yi-30% yeflethi yelangatye kwiplastiki. , I-PSF ngama-30%, i-PA66 ngama-29%, i-MPPO yi-28%, i-PC i-25%).
. Kwi-fiber fiber eqinileyo kuya kuphucula amandla amakhulu, ukusuka kwi-27J / m ukuya kwi-76J / m, ukwanda kwamaxesha ama-3; Amandla e-subile ukusuka kwi-6MPA ukuya kwi-137MPA, ukunyuka kwamaxesha oku-1. Ubungqongqo be-PPS kukuphakama kakhulu, kunqabile kubunjineli beeplanga zobunjineli. I-PPS emsulwa igoba i-modululus ukuya kwi-3.8gpa, uhlengahlengiso lwe-Inorganic lunokufikelela kwi-12.6gpa, ukwanda kwamaxesha ama-5 ngaphezulu. Kwaye ingqumbo ye-PPO eyaziwayo yi-2.55gpa, iPC kuphela i-2.1gpa. I-PPS phantsi kokunyangwa komthwalo, ubunzima obukhulu; Ukunganyangeki okuphezulu, isixa se-abrasion ye-RPM yayo eyi-1 000 yi-0.04g, izele yi-F4 kunye ne-molybdenum kukunganyaniseki kuya kuphuculwa; I-PPS ikwanenqanaba elithile lepropathi yokuzithoba. Iipropathi zoomatshini zemvakalelo yobushushu be-PPS inokuba incinci.
. Ukuxhathisa ubushushu kuya kuthelekiswa ne-PI, yesibini kuphela kwiplastiki ye-F4, engaqhelekanga ekuthengiseni iplasitiki.
. I-PPS Ukuchasana kwe-Arc ilungile, ithelekiswa ne-theristics ye thermoset. I-PPS isetyenziswa kwizixhobo zombane zokufakelwa, idosi yayo inokuchazwa malunga ne-30%.
. I-PPS iyazinza ezininzi kwii-Acids, ii-esters, iKeynes, i-phenolsbonsbons, i-qddrocarbles, i-hidrocarbons, i-oxdrocarbons, i-oxidic acid, i-witric acidi, kwaye I-Sodium Hypochlorite, njl.
Okwesibini, ubungakanani besicelo
. Enjengasekho endaweni yemveliso yentsimbi ye-cylinder yokuphelisa ivalves kunye neempembelelo zempompo, umlamli we-Pneumatic Syn.
. Ilungele izinto ezinobushushu ezinobushushu ngamaqondo obushushu aphezulu ngaphantsi kwama-200 ℃; Ingasetyenziselwa ukwenza iiverarators kunye neenjini kunye ne-shab-shabu, oombane, oombane bombane, abakhohlakeleyo kunye neebhlos, njl.; Ingasetyenziselwa indawo yokuhlala i-voltage ephezulu kunye neziseko, izithuba zesiphelo kunye neebhodi zesiphelo kwithelevishini; Ikwasetyenziswa kwiShishini le-elektroniki ekwenzeni abavelisi, abaphunga abaphumeleleyo kwaye badlulayo, abathwali basesekethe abahlanganisiweyo nendlu. kunye ne-fooll, abathwali basesekethe abahlanganisiweyo; Ukusetyenziswa kwendlela ephezulu kakhulu yokusebenza, ukwenziwa kwesakhelo se-H-dieding se-H-seard kunye ne-caprimmer kunye namandla okuthoba.
. Hlela iindlela zokulungisa ii-PPS
I. Iimpawu zokwenza
Abavelisi be-resin babonelela nge-PPS kumgangatho ophantsi (4000 ~ 5000), i-crystallinity ephezulu (7%) yomgubo omhlophe, le PPS icocekile ingenakufanekisela ngokuthe ngqo, inokusetyenziselwa ukutshiza. Isetyenziselwa ukubumba kweplapthi, kufuneka kukhenketho kunyango lokucofa, ukuze i-viscosity ye-inyibilike inyuka. Ukucofa ngokunqamlezayo emva kokunyibilikisa i-10 ~ 20 kufanelekile; I-GIBER FIBER FIRTERFROFROFFUNCRUND GET I-Index ye-PPS inokuba nkulu, kodwa ingabi ngaphezu kwe-200.
Indlela ye-PPS yokudibanisa inomnqamlezo onqamlezileyo kunye nokudityaniswa kweekhemikhali zeekhemikhali, ukucofa ngokusekwe ngokusisiseko. Ukunxibelelanisa i-thermal-ukunxibelelanisa amaqondo obushushu anqamlezileyo ye-150 ~ 350 ℃, ngezantsi kwe-150 ℃ ayinxibelelani, ngaphezulu kwe-350 ℃ yenzekile kwinqanaba eliphezulu lokudibanisa, kodwa kukhokelela kubunzima bokulungisa. Ukuncoma i-Chemical Classword ukongeza ukukhuthaza ukunkcima, iindidi ezithile ze-zusis, kukhokelela kwi-oxide, i-menis. I-PPs nangona inqamleza, kodwa ulwelo lwenkcitho aluninzi; Ke ngoko, inkcitho inokusetyenziswa kathathu; I-PPS ngokwayo ikhutshelwe i-mold, ayinakho ukujoyina iarhente yokukhupha amanzi I-PPs emva konyango lobushushu inokuphucula inqanaba le-crystallies kunye neqondo lobushushu lobushushu, iimeko zokunyanga ezihlanjululweyo zezi: Amaqondo obushushu 204 ℃, ixesha lama-30min.
II. Iindlela zokulungisa
. Iimeko zeNjongo zokuGqibela iiNqaku, Iqondo lobushushu, i-PPS ecocekileyo 280 ~ 330 ℃, 40% gfpps 300 -350 ℃; ubushushu bozzzle, i-PPS ecocekileyo 305 ℃, 40% gfpps 330 ℃; Iqondo lobushushu eli-120-180 ℃; Ingcinezelo yenaliti, i-50-130 Mpa.
. Iqondo lobushushu le-barrel 300-340 ℃, iqondo lobushushu lomzimba wokudibanisa 320-340 ℃, ubushushu bomlomo bubumba i-300-30 ℃.
. Ishushu icinezela ubushushu be-PPS ecocekileyo malunga ne-360 ℃ ye-15min, i-GFPPs malunga ne-380 ℃ ye-20min; Uxinzelelo lokubumba lwe-10 ~ 30MPA, ukupholisa ukuya kwi-150 ℃.
. I-PPS ithatha inxaxheba kubushushu bonyango lwe-300 ℃ okanye ngaphezulu, ukugcina ubushushu be-30min.
