Polyisobutlulen (PIB)waa midab aan midab lahayn, aan dhadhamin lahayn, oo aan sun lahayn ama shey adag, iska caabbian kuleyl, iska caabbinta cimilada, iska caabbinta cimilada, iska caabbinta cimilada, iska caabbinta cimilada, iska caabbinta aashitada iyo kiimikooyinka kale waxqabadka wanaagsan. Polysobutlulene waa midab aan midab lahayn, ur la'aan, aan sun ah isbarobutlumener-ka. Sababo la xiriira hababka diyaarinta kala duwan iyo xaaladaha teknolojiyada, cabirkii farsamada ee molutalar ee polyisobutluylene waxay ku kala duwan tahay farabadan. Inta badan culeyska molikal ee sheyga ayaa gaaraya in ka badan 10,000 ilaa 200,000 oo 200,000 ah oo laga soo rogi doono dareere qaro weyn ilaa badh-adag, ka dibna u gudbinta elastom-u eg caag ah. Polylobutlene waa u adkaysata aashitada, aashila, cusbo, biyo, ozone iyo gabow, oo leh hawo aad u wanaagsan iyo tuubbada korantada.
Guryaha kiimikada:Midab la'aan ah oo loo maro iftiinka dareeraha ee khafiifka ah ee jahawareerka ah ee jaranjarooyinka huruud ah ee jaranjarada ah Dhamaan ur aan u ordayaan, udgoon ama ur waxyar oo caraf ah. Celcelis ahaan culeyska molikalalbalar waa 200,000 ~ 87 milyan. Ku-milma Benzenebook iyo Diisubutyl kiimikada, waxaa lagu fahmi karaa polyvinyl acetate, wax, iwm. Sonkorta cirridka waxay leedahay jilicsan heerkul hooseeya, waxayna leedahay heerkul aad u sarreeya si ay uga dhigto qaladaadka polyvinyl ee polyvinyl acutate marka ay qabow tahay, cimilo kulul iyo jilicsanaanta xad-dhaafka ah marka ay buuxiso heerkulka afka.
Codsiyada:Pib waxaa caan ku ah qaabkiisa wanaagsan ee xidhiidhkiisa iyo dhajinta, kuwaas oo badanaa loo isticmaalo adhesha, jaakad, iyo sealants. Sifooyinka Pib-u eg ee guryaha ayaa ka dhigaya xulasho aad u fiican oo loogu talagalay qoritaanka iyo codsiyada isku xirka, maadaama ay ka caawinayso bixinta dammaanad adag oo waarta oo ku saabsan meelo badan. Ka sokow adeegsigeeda wax ku oolka ah, pib waxaa badanaa loo isticmaalaa in loogu tala galay waxyaabaha la isku qurxiyo iyo waxyaabaha daryeelka shakhsiyadeed ay sabab u tahay guryaha fadhiya ee aad u fiican. Maaddada waxaa badanaa lagu daraa maaddooyin kale si ay u abuuraan badeecad leh qaab gaar ah oo ay dareemaan.
Pib wuxuu leeyahay codsiyo fara badan oo kala duwan oo ku saabsan warshadaha cuntada sidoo kale. Maaddada waxaa badanaa loo isticmaalaa sidii dhumuc weyn, xasilooni, iyo emulsifier ku saabsan cuntooyinka la warshadeeyay. Pib wuxuu kaloo gacan ka geysan karaa hagaajinta qaabeynta iyo joogteynta alaabada sida jalaatada, xanjada, xanjada, iyo alaabada la dubay. Awoodda PIB ee PIB ayaa ka dhigaya qayb muhiim ah oo ku saabsan soosaarayaasha warshadaha cuntada.
Pib sidoo kale si weyn ayaa loogu isticmaalaa warshadaha caafimaadka. Guryaha aan sun-sunta ahayn ee maandooriyaha ayaa ku habboon in lagu isticmaalo codsiyada caafimaadka. Maaddada waxaa badanaa loo isticmaalaa xasillooni ahaan inta lagu dhex jiro tallaallada, iyo sidoo kale qayb ka mid ah dawooyin badan. Dabeecadda Pib-ga Pib-ga ayaa ka caawisa in ay u hogaansamaan maqaarka, taasoo faa'iido u leh soo saaridda dhajinta caqabadaha caafimaadka.
Astaamaha:Polyibutlene waxay leedahay astaamaha kiimikada ee xeryahooda hydrocarbon ee buufiska ah, oo dhinaca methyl swood kooxeed waa mid si adag u xidhma qaybinta sumadaha, taas oo ah polymer u gaar ah. Isku-darka gobolka iyo guryaha polyisobutylne waxay kuxirantahay miisaankeeda molikalalba ah iyo qaybinta miisaanka molikal. Marka celceliska celceliska celcelis ahaan culeyska molikal uu yahay inta u dhexeysa 70000 ~ 90000, poljisobutylen wuxuu ka beddelaa dareeraha isugeynta adag ee adag. Guud ahaan, sida ku xusan cabirka culeyska molisobutluylene wuxuu u qaybsan yahay taxanaha soo socda: Miisaaniyadda Molecalar ee Polyisautlel (celcelis ahaan celcelis ahaan miisaanka molikalulal = 200-10000); Miisaan dhexdhexaad ah oo molisobutlutlene (celcelis ahaan celcelis ahaan miisaanka molikalar = 20000-45,000); Miisaanka Molecalar ee Molecaululel Polyiutlene (celcelis ahaan celcelis ahaan miisaanka molikalar = 75,000-600,000); Miisaanka Moleculal Milkezutene (tirada celceliska isku-dhafka ah ee isku-dhafka ah ee ka weyn 760000).
1. Xadhig hawada
Mid ka mid ah astaamaha ugu wanaagsan ee polyiputene waa hawo aad u fiican oo adag. Sababta oo ah jiritaanka laba koox methyl oo beddelan, dhaqdhaqaaqa silsiladda molikalalar waa mid gaabis ah oo mugga bilaashka ah waa yar yahay. Tani waxay keenaysaa in ay ku kala jajaban tahay kala-goysyo badan oo kaladuwan iyo gaas gaas.
2. Xallinta
Polyrobutlene-ka ayaa ku milmay hydrocarbon, basromac-ka, shinwene, naphthene, saliida macdanta, hydrocarbon iyo kaarboon-monosullfide. Qayb ahaan ku milmay khamriga sareeya iyo farmaajooyinka, ama barar aalkolo, aashitada, monones, ketones iyo saliidaha kale iyo khudradda, ee bararka iyo khudradda, ee bararka, Ku dhexjil khamriga khamriga (sida methanol, ethanol, itheropyl aalkolo, glyylen glycol iyo cometoplne glycol), sida acetone, methonetthyltyl, acetic acid acetic.
3. Cadaadiska kiimikada
Polyisabutlene waa u adkaysata aashitada iyo alkali. Sida ammonia, 60% hydrofluoric acid, hoggaanka hydrofluric acid, hoggaanka hydrofluric acid, waxay hogaamisaa xalka aquetate, boqolkiiba 8% sodium hydsuric acid, oo ah 38% sulturic acid + 14% nadaafadeed, kama horjoogsan karo nabaad-guurka oxidayaasha xoog leh, oktor-ka kulul ee kulul (sida 60% potassium) Peppangandate), qaar ka mid ah kuleylka ayaa uruursan aashitada dabiiciga ah (sida 373k acetic acid) iyo halogens (forindine, koloriin, cidlo).

Kaydinta: Ku keydi meel qabow, hawo leh, meel qalalan oo leh ilaalin qorrax-celin inta lagu jiro gaadiidka.
Gabagabadii, Pib waa walax qiimo leh oo leh codsiyo fara badan oo ku saabsan warshadaha kala duwan. Guryaha aad u fiican oo sharafta leh iyo dhabarka, iyo sidoo kale fadhiya iyo awooddeeda, waxay ka dhigtaa mid ku habboon codsiyada isku qurxida, daryeelka shakhsi ahaaneed, cuntada, iyo warshadaha caafimaadka. Sida iibiyaha hogaaminta pib, waxaan u heellan nahay inaan u siino macaamiisheenna alaabada iyo adeegyada tayo sare leh si aan ula kulanno baahiyahooda warshadaha.
