Umbhobho wamanzi ashushu nabandayo we-PB
Intshayelelo yePB Hot and Cold Water Pipe
Umbhobho wePolybutene (PB) yipolymer enemolekyuli eninzi. I-resin ye-PB yinto eyenziwe nge-polymer eyenziwe nge-butene-1. Inobunzima obukhethekileyo be-0.937 g/cm3 crystal, engumzimba owahlukeneyo onokuguquguquka. Yeyemveliso yetekhnoloji ephezulu yezinto zekhemikhali eziphilayo. Kwaye inokumelana nobushushu obuphezulu, ukuqina, uzinzo lweekhemikhali kunye ne-plasticity. Ayinancasa, ayinatyhefu, ayinavumba, inomlinganiselo wobushushu ukusuka kwi--30°C ukuya kwi-+100°C, kwaye ayibanda, ayitshisi ubushushu, ayitshisi uxinzelelo, ayigqwali, ayiboli, ayikhuli, kwaye inobomi obude (iminyaka engama-50-100). Kwaye ineempawu zokumelana nokuguga ixesha elide. Yenye yezona zinto zekhemikhali ziphambili kwihlabathi. Isetyenziswa kakhulu kumazwe amaninzi ehlabathini. Kwaye inegama elithi "igolide kwiplastiki".
Imibhobho yamanzi abandayo namanzi ashushu ekumgangatho ophezulu ye-PB (polybutylene) inemveliso ezingama-24 iyonke. Yahlulwe yaba ziinkcukacha ezi-4 ukusuka kwi-dnl6 ukuya kwi-dn32. Ngokweechungechunge zemibhobho, yahlulwe yaba ziichungechunge ezintandathu: i-S10, i-S8, i-S6.3, i-S5, i-S4 kunye ne-3 .2..
Uhlu lweePB Hot and Cold Water Pipe
Izinyibilikisi zenkunkuma eziphilayo eziveliswa kwishishini le-semiconductor ziyacocwa kwaye ziphinde zisetyenziswe phantsi kweemeko zenkqubo ezihambelanayo ngesixhobo sokulungisa ukuvelisa iimveliso ezifana ne-stripping liquid B6-1, i-stripping liquid C01, kunye ne-stripping liquid P01. Ezi mveliso zisetyenziswa kakhulu ekwenziweni kweephaneli zokubonisa i-liquid crystal, iisekethe ezihlanganisiweyo ze-semiconductor kunye nezinye iinkqubo.
Iimpawu zePB Hot and Cold Water Pipe
1.Ilula, iguquguquka kwaye kulula ukuyakha. Ubunzima bombhobho we-PB bumalunga ne-1/5 yobo bombhobho wentsimbi egayiweyo. Iguquguquka kwaye kulula ukuyiphatha. Ubuncinci berediyasi yokugoba yi-6D (D: umbhobho ongaphandle ububanzi). Isebenzisa uqhagamshelo olushushu olunyibilikayo okanye uqhagamshelo loomatshini, olulungele ukwakhiwa.
2. Ihlala ixesha elide, ayinabungozi kwaye ayinabungozi. Ngenxa yobunzima bayo obukhulu beemolekyuli, ulwakhiwo lwayo lweemolekyuli luzinzile. Ayinabungozi kwaye ayinabungozi kwaye inobomi benkonzo obungaphantsi kweminyaka engama-50 ngaphandle kwemitha ye-ultraviolet.
I-3.t inokumelana kakuhle neqabaka kunye nobushushu. Nokuba ikwi--20°C, inokumelana kakuhle nobushushu obuphantsi. Emva kokunyibilika, umbhobho ubuyela kwimo yawo yokuqala. Phantsi kwe-100℃, zonke iinkalo zokusebenza zisagcinwa kakuhle.
4.Ineendonga zemibhobho ezigudileyo kwaye ayinamaqondo aphezulu. Xa ithelekiswa nemibhobho eqinisiweyo, inokunyusa ukuhamba kwamanzi nge-30%.
5. Kulula ukuyilungisa. Xa umbhobho we-PB ugqunywe, awubotshelelwanga kwikhonkrithi. Xa wonakele, ungalungiswa ngokukhawuleza ngokutshintsha umbhobho. Nangona kunjalo, kungcono ukusebenzisa indlela ye-casing (umbhobho ongaphakathi kwipayipi) yokugquma imibhobho yeplastiki. Okokuqala, gquma umbhobho we-PB ngombhobho we-PVC ogqunywe ngodonga olunye, uze uwugqume, ukuze kuqinisekiswe ukugcinwa kwexesha elizayo.
