Udini yeplastiki ekhaya.

Iiplastiki ngoku ke ixhaphake kakhulu kubomi bethu bemihla ngemihla. Plastic bokwenziwa izinto ezahlukeneyo zezithuthi, izakhiwo, izixhobo zombane, kunye nempahla, neenkamba, neempahla kakhulu ngakumbi. Kudla olungisa plastiki ekhaya isetyenziswa njenge izinto ekrwada ukuvelisa ezahlukeneyo izinto eziluncedo.

Zonke iiplastiki zisetyenziselwa ukuvelisa iimveliso zasekhaya, yahlulwe ngamaqela amabini: thermoplastic kunye thermosetting.

Thermosets luphawulwa yobulukhuni ubuninzi kunye plasticity ubuncinane evumela ukuba inganyibiliki okanye athambe xa itshiswe.

Xa itshiswe ngeqondo ukuya thermoplastics ethile ubushushu, bangcungcutheke, kodwa xa kubanda kwakhona ziqine. Le ipropati yenza thermoplastics inaliti yokubumba ekhaya kwaye wenze iinkcukacha.

Yintoni na ke ukubunjwa iiplastiki? Indlela weplastiki yenziwe ekhaya?

iplastiki ekhaya kukwazi ukwakhiwa ngale ndlela ilandelayo. Kufuneka ube kwimbuphu yesarha oluxubeneyo ngokupheleleyo ecikizekileyo Magnesite kwi ratio 2: 1, baluphose umxube umxube ka 0.1% wemagniziyam chloride baxhaya ukuze ufumane karhulumente pasty. Ukuze ufumane iinkcukacha iiplastiki ezo zisetyenziswa ngendlela esisiseko - ziphene yokubumba ekhaya ukumila kakuhle. Ngexesha Ukuqinisa, le yeplastiki uya kuba ngamandla kakhulu aphakamileyo ukuthobela elungileyo kunyango, oko kukuthi, akukho nzima ukubaqhelisa, wabona, aphathe isixhobo esirhabaxa okanye ifayile.

Kuyenzeka ukuvelisa zeplastiki ngenye indlela. Kuyimfuneko ukuba ukuxuba uthuli iinkuni ecikizekileyo phantsi talc kwi umlinganiselo 5: 2 uze ugalele glue uzilungiselele kusengaphambili samagama yakhe. Le ngcina kufuneka ukuyondelelana kwendlela cream zamafu. Lo mxube ngenxa yaba inkathazeko eziyimfuneko ukuze ufumane karhulumente pasty. Afanelekileyo ukwazisa umxube 2.1 inxalenye ngokomthamo okanye umanyolo alamu, ekukhuseleni ngokuchasene nokuvunda kwaye neoli yokomisa zendalo, inika ductility kwalo. ukuba oyifunayo, plastiki na umbala. Ukuze oku kufuneka zongezwe ukwakhiwa iiplastiki aniline ngedayi umbala oyifunayo. Ukuze ufumane iinkcukacha indlela yokuvelisa - ekhupha yeplastiki kwikhaya ukumila kakuhle. Ukwandisa amandla iiplastiki ngexesha lokuveliswa endaweni kulu wathulula nitro eqinileyo okanye nitrocellulose lacquer kulo mxube. Iinkcukacha nazo ngokwenza.

iimpawu olungileyo iplastiki, nto ilungisiwe ukususela ziqendwana zilandelayo: kulu iphepha ubunzima owomileyo / ngumchweli owomileyo kaThixo / ecikizekileyo besila netshokhwe / glycerol / ethanol / imbola owomileyo, zixubene ngokwezi iindawo ngokobunzima 5/28/60 / 2.5 / 3, 5/1.

It Utyunyuziwe ngamandla ubunzima olulophu iphepha ugalele exutywe iglu samagama yakhe. Ngexesha amachiza kufuneka ngokuthe kulawulwa glycerol, itshokhwe, imbola kunye notywala, nangoku ukuxuba oko. Iindawo zalo mxube zisetyenziswa ukulolonga iiplastiki apha ekhaya. Le imveliso ezinemibala, xa idityaniswe ngomxube aniline.

Phenol-formaldehyde iiplastiki nayo nzima ukupheka ekhaya. Kufuneka athathe crystalline (phenol) hydroxybenzene okanye analogs kunye nesisombululo zolwelo ka-40% formalin. carbolic acid kanzulu is okwazi ngokupheleleyo indawo phenol. Kuyimfuneko ukuba ukuxuba phenol crystalline (20g) kunye formalin (30 g), ukudibanisa zehydrochloric acid wamandla (30 amathontsi). Endaweni yoko, i phenol ingasetyenziselwa carbolic acid (40ml). Lo mxube kufuneka ngumdla shushu uyipheke, kwaye uya kuba ukuyondelelana kwendlela yiglasi kunye viscous. Ubunzima kubangele ukuba uthululele ukungunda imizuzu engama-30 emva koko umxube kwifomu emanzini abilayo imizuzu 10-15. Ngoko uyakwazi ukususa i imveliso ukusuka sokubumba. Ngaloo wafumana resin - yinto yeplastiki thermosetting kunye nombala obomvu, a lukhuni kunye namandla. Ukusuka kunokwenzeka ukuvelisa iindawo ezinjongo ukuba phantsi imithwalo ezibalulekileyo.
