Ingxowa yomgqomo luhlobo lokuqonda iyunithi yesikhongozeli, ikwaluhlobo lwesikhongozeli sokupakisha sothutho esiguquguqukayo.Isetyenziswa kakhulu ekutyeni, ukutya okuziinkozo, amayeza, iikhemikhali, iimveliso zamaminerali kunye nezinye i-powdery, i-granular, ibhloko yokuthutha iimpahla kunye nokupakishwa.Kukwakho neentlobo ezininzi zeebhegi zesikhongozeli, iibhegi zamalaphu ezigqunyiweyo eziqhelekileyo, iibhegi zamalaphu eresin, iibhegi ezihlanganisiweyo njalo njalo.Ke, luhlobo luni lwemeko engqongileyo ezisetyenziselwa iingxowa zeekhonteyina?Leliphi iqondo lobushushu elinokumelana neengxowa zesikhongozeli?Landela uXiaobian kunye ukuze niyiqonde!
Ingxowa yempahla ekrwada
Isitya sisitya seplastiki esiguquguqukayo esine-polypropylene kunye ne-polyethylene resin njengezinto eziluhlaza, umthamo wayo ongaphantsi kwe-3m3 kunye nobunzima bokuthwala bungaphantsi okanye bulingana neetoni ezi-3.
polypropylene
Indawo yokunyibilika 165℃, ithambe malunga ne-155℃;
Ubushushu bokusebenza buqala kwi -30°C ukuya kwi-140 °C.
Iyakwazi ukumelana nokugqwala kweasidi, ialkali, isisombululo setyuwa kunye neentlobo ngeentlobo zezinyibilikisi eziphilayo ezingaphantsi kwe80℃, kwaye zinokubola phantsi kobushushu obuphezulu kunye ne-oxidation.
i polythene
Indawo yokunyibilika i85℃ ukuya kwi-110℃, enokumelana nobushushu obuphantsi;
Ubushushu bokusetyenziswa bunokufikelela kwi-100 ° C ukuya -70 ° C, ukuzinza kakuhle kweekhemikhali, ukuchasana nobuninzi be-asidi kunye nokhukuliseko lwesiseko (alukwazi ukumelana ne-asidi eneempawu ze-oxidizing)
Ubushushu bokusebenzisa ingxowa yesingxobo?
Luthini uluhlu lweqondo lobushushu leengxowa zesikhongozeli ezenziwe ngepolypropylene kunye nepolyethylene?
Ngokomgangatho wesizwe we-GB/T10454-2000, ubushushu bovavanyo lokumelana nokubanda kwengxowa yesikhongozeli yi-35℃.
Beka ingxowa yesikhongozeli kwi--35℃ engaguqukiyo kwibhokisi yobushushu ngaphezu kweeyure ezi-2, kwaye emva koko usonge imveliso yovavanyo kwisiqingatha ukuya kwii-degrees ezingama-180 ukujonga ukuba i-substrate imathiriyeli yonakele, iqhekekile kunye nezinye iimeko ezingaqhelekanga.
Ubushushu bovavanyo lokumelana nobushushu yi-80℃.
Faka isicelo somthwalo we-9.8N kwimveliso yokuvavanya kwaye uyibeke kwi-oven kwi-80 ℃ nge-1h.Ngokukhawuleza emva kokuthatha imveliso yovavanyo, yahlula iziqwenga ezimbini zovavanyo ezityhutyhayo kwaye ujonge umphezulu wokubambelela, iintanda kunye nezinye iimeko ezingaqhelekanga.
Ngokomgangatho wovavanyo, ingxowa yesikhongozeli ingasetyenziswa kwindawo ye--35 ° C ukuya kwi-80 ° C, kodwa ayikhuthazwa ukuba isetyenziswe ixesha elide kwiindawo eziphezulu kunye nezisezantsi zokushisa.
