IPB Umbhobho waManzi ashushu nabandayo
Intshayelelo yePB yaManzi ashushu nabandayo
Umbhobho wePolybutene (PB) yipolymer engasebenziyo yemolekyuli ephezulu. I-PB resin yi-polymer material synthesized from butene- 1. Inobunzima obukhethekileyo be-0.937 g / cm3 crystal, engumzimba ohlukeneyo kunye nokuguquguquka. Iyeyemveliso ye-high-tech yezixhobo ze-organic chemical. Kwaye inokumelana nokushisa okuphezulu, ukuqina, ukuzinza kweekhemikhali kunye neplastiki. Ayinancasa, ayinayo ityhefu, ayinavumba, inomlinganiselo wobushushu obuphakathi kwe -30 ° C ukuya +100 ° C, kwaye ayixhathisi yingqele, ikwazi ukumelana nobushushu, ikwazi ukumelana noxinzelelo, ayivuthi, ayinamhlwa, ayikhuseli, kwaye inobomi obude (iminyaka eyi-50- 100). Kwaye ineempawu zokumelana nokuguga kwexesha elide. Sesinye sezona zixhobo zekhemikhali eziphuma phambili emhlabeni. Isetyenziswa kakhulu kumazwe amaninzi ehlabathini. Kwaye inegama elithi "igolide kwiplastiki".
I-PB (i-polybutylene) iphezulu imibhobho yamanzi abandayo kunye namanzi ashushu ineemveliso ezingama-24 zizonke. Ukwahlulwe kwiinkcukacha ezi-4 ukusuka kwi-dnl6 ukuya kwi-dn32. Ngokutsho koluhlu lwemibhobho, ihlulwe kwiichungechunge ezintandathu: i-S10, i-S8, i-S6.3, i-S5, i-S4 kunye ne-3 .2..
Ukuhlelwa koMbhobho waManzi ashushu kunye nabandayo we-PB
Inkunkuma ye-solvents ye-organic eveliswe kushishino lwe-semiconductor iyacocwa kwaye ihlaziywe phantsi kweemeko zenkqubo ehambelanayo ngokusebenzisa isixhobo sokulungiswa ukuvelisa iimveliso ezifana nokuhlutha ulwelo lwe-B6-1, ulwelo oluhluthayo lwe-C01, kunye nolwelo oluhluthayo lwe-P01. Ezi mveliso zisetyenziswa ikakhulu ekwenzeni iipaneli zokubonisa ikristale elulwelo, iisekethe ezidityanisiweyo zesemiconductor kunye nezinye iinkqubo.
Iimpawu zePB ezishushu nezibandayo zaManzi
1.Bubunzima obulula, buguquguqukayo kwaye kulula ukubukha. Ubunzima bombhobho we-PB bumalunga ne-1/5 yalowo wombhobho wentsimbi. Iyabhetyebhetye kwaye kulula ukuyiphatha. Ubuncinci beradiyasi yokugoba yi-6D (D: umbhobho wedayamitha yangaphandle). Yamkela uxhulumaniso olushushu olunyibilikayo okanye uqhagamshelo lomatshini, olulungele ukwakhiwa.
2. Inokuqina okulungileyo, okungeyona ityhefu kwaye ayinabungozi. Ngenxa yobunzima bayo obuphezulu bemolekyuli, ubume bayo bemolekyuli buzinzile. Ayinatyhefu kwaye ayinabungozi kwaye inobomi benkonzo obungekho ngaphantsi kweminyaka engama-50 ngaphandle kwemitha ye-ultraviolet.
I-3.t inokumelana kakuhle neqabaka kunye nokumelana nobushushu. Nokuba ku--20 ° C, inokugcina ukuxhathisa okuhle kobushushu obuphantsi. Emva kokunyibilika, umbhobho ubuyela kwimo yawo yangaphambili. Phantsi kwemeko ye-100℃, yonke imiba yokusebenza isagcinwa kakuhle.
4.Ineendonga zepayipi ezigudileyo kwaye ayilinganisi. Xa kuthelekiswa nemibhobho yegalvanized, inokunyusa ukuhamba kwamanzi ngama-30%.
5.Kulula ukulungisa. Xa umbhobho we-PB ungcwatywa, awubophekanga kwikhonkrithi. Xa ibonakaliswe, inokulungiswa ngokukhawuleza ngokutshintsha umbhobho. Nangona kunjalo, kungcono ukusebenzisa i-casing (umbhobho kwipayipi) indlela yokungcwaba imibhobho yeplastiki. Okokuqala, vala umbhobho wePB ngombhobho wePVC wodonga olunye, uze uwungcwabe, ukuze ulondolozo lwexesha elizayo luqinisekiswe.
