Yintoni wasebenzisa ngamaplanga bakelized?

Emva ngo 1909 ubhaliswe patent yokuqala yehlabathi ukwenzela ukwenziwa zeplastiki. Ekuqaleni, oososayensi kuhlanganiswa a phenol-formaldehyde resin, yaye kuphela emva kokuba ufumene Polymer yokuqala yehlabathi. Okokuqala, into entsha uye wabizwa ngokumangalisayo yi ekhemisi "oksibenzilmetilenglikolangidrid", kodwa ingqondo namandla, yaye emva koko wazalwa i "Bakelite". Enyanisweni, lo mhla lusuku xa kwabakho ngamaplanga bakelized.

Noko ke, into entsha ezithandwayo Akucaci: ekuqaleni lalisetyenziswa oko kuphela kwimveliso insulators. Kodwa emva kweminyaka embalwa, oko arhola ingqalelo abameli neemoto nempahla: Bakelite waba oluthambileyo kakhulu yaye izinto angabizi, ezilungele imveliso mass.

Wadalwa kamsinya ucwecwe bakelized, eseyiphantse ayitshintshanga ikhona unanamhla. Oku kusekelwe ezinde ngokwenene ezikumgangatho ophezulu, qhiwu phenol formaldehyde ivanishi. Ngenxa yoxinzelelo amaqondo obushushu, nto leyo iimeko eziyimfuneko ukuze kuveliswe le nto, kunokwenzeka ukufezekisa phantse-100% degree of ukumitha. Phenols ngokwabo ezingenakunyibilika kwaye ukuwonakalisa impilo yomthengi, kodwa ngempumelelo ekuthinteleni ukuhlasela ezinzwaneni of ngamaplanga. Ngenxa yoku, eli isiphumo esifanayo phantse akuthethi ibole.

Phezu kwako nje elula kakhulu kwimveliso, ovelisa ngamaplanga bakelized neneempawu amandla enza ukuba uluntu phantse ukukhuphisana nokuqhubekayo. Kodwa iindleko linzulu kakhulu, nto leyo inegalelo ukuthandwa kwalo mbandela phakathi kwabakhi.

Ukuba ufunda ngenyameko, mhlawumbi akuyi kuba kuni iindaba yokuba zingasetyenziswa nkqu okungqongileyo nakwezona zinzima iimeko. Kuye nje ukumelana eliphezulu ukufuma, kodwa unesifo impembelelo embi of iindawo kwemichiza ndlongondlongo. Ngenxa yoku, oko kudla kunokubonwa kwiindawo ezinjalo exotic, yona enqanawa. Kakade ke, kwiimeko ezinjalo, a ngamaplanga ekhethekileyo ngamanzi-resistant bakelized ixesha elide nako ukumelana nkqu ifuthe olwandle lovukelo.

Kwakhona zingasetyenziswa ukuba formwork ngebhegi eziphathekayo, njengokuba nkqu embalwa imijikelo eyahlulayo wahlala ngaphandle naziphi na iingxaki. Qokelela shuttering onjalo ilula, nasezindongeni zayo anencasa ukuvumela ukufumana cap output phantse uqwalaselo ogqibeleleyo. Ukuqwalasela kwakhona conductivity yayo esezantsi thermal, uya kulahlekelwa ubushushu phi, kusetyenziswa ubugcisa ubusika zokufudumeza eziphathekayo xa zingena. Ngokufutshane, i ngamaplanga elula bakelized unako ukusindisa eninzi imali yeendleko ukunyuka ukuya kuthenga kuyo.

Ubukhulu ezinkulu unekhasi elisezantsi le nto akubikho mfuneko ubuncinane inani amalungu. Ukuba ngokufanelekileyo kwaye ngenyameko kusetyenziswa, omnye formwork kakhulu nako ukumelana malunga namashumi amathathu kwiziseko! Okwangoku ngamaplanga bakelized FBS brand eveliswa kwilizwe lethu. ukukhululwa yakhe izityalo abazibandakanya Tyumen kunye Nizhny Novgorod, eyaziwa umgangatho ophezulu iimveliso zayo.
