Umlinganiselo wobushushu weVicat ulinganisa njani ukumelana nobushushu kombhobho we-UPVC kunye nevalve?
Umlinganiselo wobushushu weVicat ulinganisa njani ukumelana nobushushu kombhobho we-UPVC kunye nevalve?
Umda wokushisa osebenzayo wevalve ye-upvc, umbhobho ngu-0-70 ℃. Ubushushu obuqhelekileyo bufanelekile ekusebenzeni kwezinto ze-UPVC. ukuba ukushisa okusebenzayo kwanda, umlinganiselo wamandla oxinzelelo lwangaphakathi kufuneka uncitshiswe. Umlinganiselo wokumelana noxinzelelo phantsi kobushushu obuhlukeneyo uboniswa kwitheyibhile elandelayo njengereferensi.
Ubudlelwane phakathi kobushushu bokusebenza kombhobho wevalve ye-UPVC kunye nokumelana noxinzelelo:
Ubushushu bokusebenza | 20 | 25 | 30 | 40 | 50 | 60 |
umlinganiselo woxinzelelo | 100 | 95 | 85 | 65 | 35 | 10 |
Ukumelana nobushushu kombhobho we-UPVC kuvavanyo oluthile lunendlela ekhethekileyo yovavanyo oluyi-Vicat yokuthambisa uvavanyo lobushushu. Okulandelayo sazisa injongo yolu vavanyo kunye neendlela zokuvavanya.
Injongo yovavanyo lwe-01: umbhobho wevalve ye-UPVC kulula ukukhubaza emva kobushushu, ukuya kwiqondo lobushushu leVicat ukulinganisa ukumelana nobushushu kombhobho kunye nevalve.
02 Izixhobo zovavanyo: Umatshini wokuvavanya iVicat
03 inkcazo yovavanyo:
(1) umboniso ubekwe kwindawo engamanzi, phantsi kwemeko yokunyuka kobushushu be-isothermal ukumisela inaliti yoxinzelelo oluqhelekileyo (indawo enqamlezayo ye-1mm2) phantsi kwesenzo se-50 N force, icinezelwe kwi-specimen lmm xa ubushushu; oko kukuthi, i-specimen's Vicat Softening Temperature ( VST ).
(2) Iqondo lokushisa lokuthambisa i-Vicat kukuvavanya ukuxhathisa ubushushu bezinto eziphathekayo, ebonisa iimpawu ezibonakalayo kunye noomatshini beemveliso kwiimeko zobushushu zesinye sezibonakaliso.
(3) Okukhona iqondo lobushushu lokuthambisa iVicat liphezulu, kokukhona uzinzo lwedimensional lungcono xa luphantsi kobushushu, kokukhona kuncinci ukuguquguquka kwe-thermal, oko kukuthi, ngcono ukuxhathisa ubushushu.
(4) iimfuno umgangatho wesizwe PVC-U umbhobho wonikezelo lwamanzi Vicat ukuthamba lobushushu ≥ 80 ℃, thina Chuanli Plastics Co., Ltd. imveliso yonikezelo lwamanzi kushishino umbhobho khemikhali valve valve Vicat ubushushu ngokubanzi 82 ~ 83 ℃. Umbhobho wokuthuthwa kwamanzi iimfuno zomgangatho wesizwe weVicat ukuthambisa ubushushu ≥ 79 ℃, thina chuanli Plastics Co., Ltd. imveliso PVC-U umbhobho wokufunxa Vicat ukuthamba lobushushu ngokubanzi 80 ~ 81 ℃.
