Inkqubo yokuvelisa kunye neempawu ezintlanu zefiber yeglasi

一、 Inkqubo yokuvelisa ifayibha yeglasi

Iifayibha zeglasi, ukuqinisa i-Fibra de vidrio compuestakunye nezixhobo zokutshintshwa kwesinyithi.Ububanzi be-monofilament buyi-microns ezininzi ukuya kwi-microns ezingamashumi amabini, ezilingana ne-1 / 20-1 / 5 yeenwele, kunye ne-bundle nganye ye-fiber strands yenziwe ngamakhulu okanye namawaka e-monofilaments.

I-Fiberglass preg ineempawu zokungatsha, ukumelana nokugqwala, ukugquma ubushushu, ukugqunywa kwesandi esilungileyo, amandla aphakamileyo aqinile, ukugqunywa kombane okulungileyo, njl. imibhobho, uthutho lukaloliwe, amandla omoya kunye neminye imimandla Ithemba losetyenziso olubanzi.

Kukho iintlobo ezimbini zenkqubo yokuvelisa i-glass fiber: ukubunjwa kwexesha-embini-indlela yokuzoba i-crucible, enye yokwenza - indlela yokudweba i-pool kiln.

Indlela yokudweba i-crucible ineenkqubo ezininzi.Okokuqala, izinto eziluhlaza zeglasi zinyibilika kwiibhola zeglasi kwiqondo lokushisa eliphezulu, kwaye iibhola zeglasi ziyanyibilika okwesibini, kwaye emva koko zitsalwe ngesantya esiphezulu ukwenza.ukuzulazula.Le nkqubo ineziphene ezahlukeneyo ezifana nokusetyenziswa kwamandla aphezulu, inkqubo yokubumba engazinzanga, kunye nemveliso ephantsi yabasebenzi, kwaye isuswe ngokusisiseko ngabavelisi abakhulu beglasi.

Indlela yokudweba i-pool kiln iyanyibilika izinto eziluhlaza ezifana ne-pyrophyllite kwisisombululo seglasi kwi-oven, isusa amaqamza omoya kwaye ithuthelwe kwi-bushing ene-porous ngokusebenzisa i-paseji, kwaye iyitsale kwi-fiber strand yeglasi ngesantya esiphezulu.I-kiln inokudibanisa amakhulu e-bushings ngokusebenzisa iziteshi ezininzi zokuvelisa ngaxeshanye.Le nkqubo ilula, igcina amandla kunye nokunciphisa ukusetyenziswa, izinzile ekubumbeni, ukusebenza kakuhle kunye nemveliso ephezulu, kwaye ilungele ukuveliswa kwemveliso ezenzekelayo ngokupheleleyo.Sele ibe yinkqubo yemveliso yezizwe ngezizwe.I-Fiberglass quoins eveliswa yile nkqubo yenza ngaphezu kwe-90% yemveliso yehlabathi.

二、 Iimpawu ezintlanu zefiber yeglasi

I-1.Ukhuseleko kunye nokukhuselwa kwendalo, khusela impilo yabasebenzi

Ifayibha yeglasi inamandla okuqina okuqinileyo, ayinamibimbi, ichasene ne-vulcanization, umsi, i-halogen-free, i-non-toxic, i-oksijini esulungekileyo, engatshiyo, kunye neempawu ezintle zokugquma.Emva kokunyanga nge-silicone, ukhuseleko lwayo kunye nokusebenza kokusingqongileyo kunokuphuculwa ngakumbi.Ukukhusela ngokufanelekileyo impilo yabantu yabasebenzi kunye nokunciphisa ukuvela kwezifo zasemsebenzini.Ngokungafaniyo neemveliso ze-asbestos, iyingozi kakhulu ebantwini nakwindalo esingqongileyo.

2.Ukumelana nobushushu obugqwesileyo

Umphezulu wei-fiberglass yokufakelwa kwe-thermal iqulethe zombini "amaqela aphilayo" kunye "nezakhiwo ezingaphiliyo".Olu qulunqo olukhethekileyo kunye nesakhiwo se-molekyuli sivumela ukuba sidibanise iipropati ze-organic matter kunye nomsebenzi we-inorganic matter.Xa kuthelekiswa nezinye izinto zepolymer, ibalasele ngokumelana nobushushu obuphezulu.Ibhondi ye-silicon-oxygen (i-Si-O) yinkqubo yekhonkco ephambili, kwaye amandla ebhondi ye-CC bond yi-82.6 kcal / g kunye namandla ebhondi yebhondi ye-Si-O yi-121 kcal / g kwi-silicone resin, ngoko. ukuzinza kwe-thermal kuphezulu, kwaye i-Chemical bonds ye-molecule ayiphuli okanye ichithakala phantsi kobushushu obuphezulu (okanye ukuvezwa kwemitha).I-Silicone ayimelani kuphela nobushushu obuphezulu kodwa kunye nobushushu obuphantsi, kwaye ingasetyenziswa kuluhlu olubanzi lobushushu.Ayitshintshi ngeqondo lobushushu, nokuba kukwimichiza okanye kumatshini womzimba.

3.Anti-splash, ukhuseleko oluninzi

Kwishishini lokunyibilikisa, iqondo lokushisa eliphakathi kwisithando sombane liphezulu kakhulu, kwaye i-spatters yokushisa ephezulu yenziwa ngokulula (njengakwishishini le-welding yombane).Emva kokupholisa kunye nokuqina, iifom ze-slag kumbhobho okanye ikhebula, eqinisa i-rubber kwinqanaba elingaphandle lombhobho okanye ikhebula kwaye ibangele ukuphuka kwe-brittle.Emva koko, izixhobo ezingakhuselekanga kunye neentambo zinokonakala.Emva kokusebenzisa i-silicone eninzi-coatediiglasi zefiberglass imikhono, ukhuseleko oluninzi lunokufezekiswa kwaye ukunyibilika kobushushu obuphezulu besinyithi esinyibilikisiweyo, ubhedu kunye ne-aluminium kunokuthintelwa ngokufanelekileyo.ukutshiza amanzi ukuphepha umonakalo kwiintambo ezijikelezileyo kunye nezixhobo.

4. Ukushisa ubushushu, ukonga amandla, ukuchasana nemitha

Kwi-workshop yokushisa okuphezulu, iipayipi ezininzi, iivalve okanye izixhobo zineqondo lokushisa eliphezulu langaphakathi.Ukutsha okanye ilahleko yobushushu inokuba nesiphumo ukuba ayigqunywanga ngezinto ezikhuselayo.I-Fiberglass inozinzo olungcono lwe-thermal kunezinye izinto ze-polymer, kwaye iyamelana ne-radiation kunye ne-thermal insulation, ukukhusela iingozi, ukunciphisa ukusetyenziswa kwamandla kunye nokuthintela ukuhanjiswa ngokuthe ngqo kobushushu ukusuka kwi-medium kumbhobho ukuya kwindawo ejikelezileyo.Imo engqongileyo igqithisa iworkshop, egcina iindleko zokupholisa.

5.Ubungqina bokufuma, ubungqina be-oyile, ubungqina bemozulu, ubungqina bongcoliseko, bandisa ubomi benkonzo yesixhobo

Ifayibha yeglasi inozinzo olomeleleyo lwekhemikhali.I-Silicone ayiyi kusabela ngeoli, amanzi, i-asidi kunye ne-alkali njl. Kwiqondo lokushisa lama-260 ° C, ingasetyenziselwa ixesha elide ngaphandle kokuguga.Ubomi benkonzo yefiberglass engenamanzikwindawo yendalo inokufikelela amashumi eminyaka.Kule meko, inokukhusela imibhobho, iintambo kunye nezixhobo kumlinganiselo omkhulu kwaye zandise kakhulu ukusetyenziswa kwazo.
