Sezingubo isixazululo ukhonkolo: kuyini nokuthi kungani uludinga

Izithasiselo okuyinto ngcono izici nosimende ukhonkolo etholwe izindlela amakhemikhali, ngokuthi plasticizers. Futhi kungenziwa wanezela hhayi kuphela isixazululo ngomumo, kodwa ngisho lapho besanda kasimende ukugaya.

Akubalulekile ukucabanga ukuthi plasticizer ngoba isixazululo usimende ukhona kuphela eyodwa version. Iqiniso liwukuthi emhlabeni kukhona omningi izinhlobo ukhonkolo, ngamunye okuyinto edinga ukuba ngcono kanye nokulungiswa izakhiwo ezithile. Noma kunjalo, babe ezinye izici ezivamile, okuyinto ihlanganisa nohlu ejwayelekile ngcono ukusebenza. Ake ubatshele:

• plasticizer kuhle ezigqulweni Kuyoba kakhulu ukunciphisa ukusetshenziswa zokwakha;
• izakhiwo kokokunamathisela ukhonkolo ayathuthuka, futhi Nokho, isilinganiso usimende namanzi, ayiguquki;
• Le isixazululo amanzi zilimaze ezingeni lokushisa ongaphakeme, futhi amandla "ebusika" inyuka ukhonkolo, ngaphezu kwalokho, ziyancipha kakhulu izindleko amalahle isixazululo noma ukusetshenziswa kwezinye reagents chemical;
• amanzi ukumelana negesi impermeability imikhiqizo siphelile is yathuthuka ngokuphawulekayo.

Ukwahlukaniswa izithasiselo

Ukuze uqonde kangcono izakhiwo zabo, kumelwe okungenani cishe ukwazi esigabeni kahle elula lapho kungase kudingeke ukuba ukhethe plasticizer ikhambi. Okokuqala, ake sixoxe bahlale ngokwahlukana, kuye ngokuthi isimiso yokusebenza:

• yelikhono noma inhibitor ukuqina aphathekako;
• modifiers lidlulisele izakhiwo olukhethekile ukhonkolo eqeda (ukumelana ukuguguleka komhlabathi, izinga lokushisa eliphakeme, usawoti, nokunye. d.).

Uma sikhuluma ngamandla isinyathelo, the plasticizer ngoba wokwakha nosimende singase sibe namandla, alungise noma ebuthaka. Ingabe ingxube mono-, bi- futhi polyvalent Izithako zokwenziwa ngokugcwele nokumbiwa.

Izinga kanye nokwethulwa ngokuyiko kwezinhlelo plasticizers

Esikhathini Ukucaciswa umkhiqizo osuphelile kuthintwa hhayi kuphela uhlobo izakhiwo plasticizer, kodwa futhi izinga usimende ngokwayo, esasetshenziswa esikhangisweni se ikhambi nomkhombe. Ethandwa kakhulu phakathi abakhi abangochwepheshe uyawuthanda imikhiqizo lenkampani Rhein-Chemotechnik GmbH (Germany).

Le isixazululo plasticizer German muhle yokusebenza kwalo ngezindlela eziningi. Ngokuyinhloko ukwenziwa izixazululo kwanoma iyiphi isigaba, uzodinga isilinganiso esiphansi lwewashi. Ngaphezu kwalokho, besebenzisa inhlanganisela ezahlukene kuphela izinhlobo eziningana izithasiselo, kungenzeka ukuba ukhethe ukulandelana elikhulu cishe kuwona wonke amabanga ngokhonkolo. Ubulula futhi ngenxa yokubakhona eliphezulu futhi imiyalelo enemininingwane.

Efingqa, singasho ukuthi plasticizer ikhambi (intengo zazo kuncike umakhi) ayikwazi kakhulu kuphela ukwehlisa izindleko zokwakha, kodwa futhi ukwandisa zabasebenzi umkhiqizo. Ngaphezu kwalokho, ukuba khona izinhlobo ezahlukene modifiers ungakwazi kalula usethe ukukhiqizwa hhayi kuphela elula esigqulweni, kodwa ngisho ezinhle izinga Foam. Sikhishwe izindleko zokwakha eminyakeni yamuva, kubalulekile ikakhulukazi hhayi kuphela izinkampani kodwa futhi abantu ngabanye.
