Yini esetshenzisiwe plywood bakelized?

Emuva ngo-1909 yabhaliswa patent wokuqala emhlabeni womshini Plastics. Ekuqaleni, ososayensi kwemiqondo a resin phenol-formaldehyde, futhi kuphela ngemva kokuba beye bathola kuqala polymer emhlabeni. Okokuqala, kwenziwe into entsha iye ngokumangalisayo ngokuthi ngu bamakhemikhali "oksibenzilmetilenglikolangidrid", kodwa ingqondo lanqoba, bese yazalwa "Bakelite". Empeleni, lolu suku kwakuwusuku kwakukhona plywood bakelized.

Nokho, into entsha ethandwa awusheshanga: ekuqaleni lalisetshenziswa ngokukhethekile ukwenziwa insulators. Kodwa ngemva kweminyaka embalwa, ke wadonsela ukunaka abamele izimboni yezimoto kanye ifenisha: Bakelite kwaba oluthambile kakhulu futhi izinto engabizi, ekahle ekukhiqizweni.

Wadalwa nje plywood bakelized, okuyinto cishe ingashintshiwe ukhona kuze kube yilolu suku. Kusekelwe eliphezulu birch yokwakha yaseGrisi, ethe njo phenol formaldehyde ukuvenisha. Banikezwe ingcindezi kanye lokushisa, okuyizinto izimo ebalulekile ekukhiqizweni yalesi material, kungenzeka ukuba sifinyelele cishe 100% degree of impregnation. Phenols ngokwabo zingaxazululeki futhi abanakubalimaza impilo umthengi, kodwa kukhona ekuvikeleni ukuhlaselwa ukukhunta plywood. Ngenxa yalokhu, umphumela ofanayo cishe akusho ukubola.

Naphezu inkimbinkimbi okwedlulele ukukhiqizwa, ithela plywood bakelized sinezici amandla ukuthi likwazi cishe ancintisane ngentuthuko yakamuva. Kodwa izindleko zalo lingaphansi kakhulu, okuyinto enomthelela ukuthandwa le nto phakathi abakhi.

Uma ufundisisa, cishe ngeke ngawe izindaba iqiniso ukuthi ingasetshenziswa ngisho ezindaweni eyinselele kakhulu. It has hhayi kuphela ukumelana umswakama, kodwa futhi ehlupheka ithonya elibi nolaka chemical ezindaweni. Ngenxa yalokhu, ngokuvamile kuyabonakala ezindaweni ezifana ezingavamile, okuyinto esemkhunjini. Yiqiniso, ezimweni ezinjalo, ipulangwe ekhethekile amanzi nemithi bakelized isikhathi eside ongamelana ngisho umthelela asolwandle esisheshayo.

Iphinde ingasetshenziswa njengendlela indaba for formwork esebenza, njengoba ngisho ambalwa asakazwe imijikelezo zigcinwe ke ngaphandle kwezinkinga. Ukuqoqa shuttering enjalo ilula, futhi izindonga zawo bushelelezi avumele ukuthola cap okukhipha cishe ukucushwa ephelele. Uma ucabangela futhi conductivity yayo ongaphakeme ezishisayo, uzolahlekelwa ukushisa ingasaphathwa, besebenzisa ubuchwepheshe of ubusika Ukushisa ukhonkolo lapho ethela. Kafushane, a plywood elula bakelized ukwazi ukulondoloza imali eningi ngesikhathi izindleko aphansi ukuze iyithenge.

Usayizi enkulu ishidi esezingeni le nto kungabi nesidingo inombolo okungenani amalunga omzimba. Uma isetshenziswa ngendlela efanele ngokucophelela, omunye formwork ukwazi ngempela ukumelana mayelana amathathu ofakwe! Okwamanje plywood bakelized brand FBS ekhiqizwa ezweni lethu. ukukhululwa wakhe izitshalo wahlanganyela Tyumen futhi Nizhny Novgorod, izinga eyaziwa eliphezulu imikhiqizo yayo.
