PB Ipayipi Lamanzi Ashisayo Nabandayo
Isingeniso se-PB Amanzi Ashisayo Nabandayo
Ipayipi le-Polybutene (PB) liyi-polymer ene-molecular inert ephezulu. I-PB resin i-polymer material eyenziwe kusuka ku-butene- 1. Inobukhulu obukhethekile bekristalu obungu-0.937 g/cm3, umzimba ohlukile onokuguquguquka. Kungokwemikhiqizo yobuchwepheshe obuphezulu bezinto zamakhemikhali eziphilayo. Futhi inokumelana nokushisa okuphezulu, ukuqina, ukuzinza kwamakhemikhali kanye nepulasitiki.
Ayinambitheki, ayinabuthi, ayinaphunga, inezinga lokushisa eliphakathi kuka -30°C kuya ku-+100°C, futhi ayikwazi ukumelana nokubanda, ukumelana nokushisa, ukumelana nokucindezela, okungagqwali, akugqwali, akubiki. , futhi inesikhathi eside sokuphila (50- 100
iminyaka). Futhi inezici zokumelana nokuguga isikhathi eside. Ingenye yezinto zamakhemikhali ezisezingeni eliphezulu kakhulu emhlabeni. Isetshenziswa kabanzi emazweni amaningi emhlabeni. Futhi Inedumela “legolide phakathi
ipulasitiki".
Ukuhlukaniswa Kwepayipi Lamanzi Ashisayo Nabandayo we-PB
Izinyibilikisi ze-organic organic ezikhiqizwa embonini ye-semiconductor ziyacwengwa futhi zigaywe kabusha ngaphansi kwezimo zenqubo ehambisanayo ngokusebenzisa idivayisi yokulungisa ukuze kukhiqizwe imikhiqizo efana nokuhlubula uketshezi lwe-B6-1, uketshezi lokuhlubula i-C01, noketshezi lokuhlubula i-P01. Le mikhiqizo isetshenziswa kakhulu ekwenzeni amaphaneli e-liquid crystal display, ama-semiconductor integrated circuits nezinye izinqubo.
Izici ze-PB Hot and Cold Water Pipe
1.Kuyisisindo esincane, kuyavumelana nezimo futhi kulula ukukwakha. Isisindo sepayipi le-PB cishe yi-1/5 yaleso sepayipi lensimbi. Iyavumelana nezimo futhi kulula ukuyithwala. Irediyasi yokugoba encane ingu-6D (D: ububanzi bepayipi langaphandle). Yamukela uxhumano lwe-hot melt noma uxhumano lwemishini, olulungele ukwakhiwa.
2. Inokuqina okuhle, ayinabo ubuthi futhi ayinabungozi. Ngenxa yesisindo sawo samangqamuzana aphezulu, ukwakheka kwawo kwamangqamuzana azinzile. Ayinabuthi futhi ayinabungozi futhi inempilo yesevisi engaphansi kweminyaka engama-50 ngaphandle kwemisebe ye-ultraviolet.
I-3.t inokumelana nesithwathwa okuhle nokumelana nokushisa. Ngisho naku -20°C, ingagcina ukumelana nomthelela wezinga lokushisa eliphansi. Ngemva kokuncibilika, ipayipi ibuyela esimweni sayo sokuqala. Ngaphansi kwesimo sika-100℃, zonke izici zokusebenza zisagcinwa kahle.
4.Inezindonga zamapayipi abushelelezi futhi ayilinganisi. Uma kuqhathaniswa namapayipi anathayela, kungakhuphula ukugeleza kwamanzi ngo-30%.
5.Kulula ukukhanda. Lapho ipayipi le-PB lingcwatshwa, aliboshelwa kukhonkolo. Uma konakala, ingalungiswa ngokushesha ngokufaka ipayipi esikhundleni. Kodwa-ke, kungcono ukusebenzisa indlela ye-casing (ipayipi epayipini) yokungcwaba amapayipi epulasitiki. Okokuqala, vala ipayipi le-PB ngepayipi likathayela elinodonga olulodwa lwe-PVC, bese uligqiba, ukuze ukugcinwa kwesikhathi esizayo
ingaqinisekiswa.
