Phula, lomwe ndi gawo lofunika kwambiri poletsa kuti madzi asalowe, ndi phula la hydrocarbon lomwe limapezeka m'mitsinje monga mchenga wamafuta ndi nyanja za phula kapena amapeza pothira mafuta osakanizika m'malo oyeretsera. Pa distillation ndondomeko monga opepuka zigawo zikuluzikulu kukwera pamwamba, katundu zigawo zikuluzikulu, kuphatikizapo phula, kugwa pansi pa ndime.

Mukachotsa tizigawo ting'onoting'ono monga mafuta a petroleum amadzimadzi, mafuta a petulo, ndi dizilo kuchokera kumafuta osakanizidwa panthawi yoyenga, gawo lotsalira limatchedwa phula. Phula la phula limatha kusintha mpaka kuchuluka kwa zinthu zosakhazikika zomwe zimatsalira mu phula losungunuka.

Phula likhoza kugwiritsidwa ntchito ngati zopangira kapena zosakaniza malinga ndi malo ogwiritsira ntchito. Itha kugwiritsidwa ntchito ngati chomangira phula lamisewu, misewu, malo oimikapo magalimoto, njira zamapazi. Amagwiritsidwanso ntchito ngati kusakaniza m'magawo omanga ndi zomangamanga kuyambira pansi mpaka padenga kuti apereke mawonekedwe abwino kwambiri oletsa madzi.

Bitumeni imatha kusinthidwa ndi ma polima kuti ipititse patsogolo magwiridwe antchito ake ndikugwiritsa ntchito ngati mitundu yosiyanasiyana yazogulitsa pakumanga. Iwo akutumikira monga chigawo chachikulu chakutsekereza madzizida mu mawonekedwe a sealants, mastics, zomatira, zokutira etc.

N'chifukwa Chiyani Bitumen Ndi Yotchuka M'gawo Loletsa Madzi?

Choyamba, phula ili ndi ndondomeko yachuma. Bitumeni, yomwe imatsalira pambuyo pothira mafuta osakanizika, imapangidwa mwachilengedwe Pamene zinthu zoyambira monga petulo, dizilo, mafuta okwera a octane ndi mafuta akuyengedwa, phula limasiyidwa.

Komanso, phula limagwira ntchito zosiyanasiyana. Imawonetsa machitidwe a viscoelastic ndi thermoplastic. Bitumeni imakhala ndi ma viscous komanso zotanuka kutengera kutentha ndi nthawi yotsegula. Pakutentha kwambiri kapena pakatha nthawi yayitali, phula limakhala ngati chinthu chowoneka bwino. Kukatentha kwambiri kapena potsitsa mwachangu phula limakhala ngati zotanuka.

Malo osungunuka a phula siwokwera kwambiri moti amatha kusungunuka mosavuta panthawi yogwiritsira ntchito. Phula limakhala ndi zomatira kwambiri, zomwe zimapangitsa kuti zinthuzo zikhale pamodzi mwamphamvu. Zonsezi zimatsimikizira kuti phula lotsekera madzi ndi imodzi mwazothandiza kwambiri mpaka malo ogwiritsira ntchito.

Kodi Zogulitsa Bitumen za Baumerk Ndi Ubwino Wake Ndi Chiyani?

Zida zotetezera madzi za phula zili ndi malo osiyanasiyana ogwiritsira ntchito. Zikomo kwaBaumerk, mutha kugwiritsa ntchito mitundu yosiyanasiyana yazinthu zotchingira madzi phula pazosowa zosiyanasiyana. Zida zotchingira madzi za phula muzinthu za Baumerk, zomwe ndi gawo limodzi kapena ziwiri zokhala ndi mawonekedwe olimba komanso amadzimadzi, zimakhala ndi zabwino zambiri.

Mwachitsanzo, polyurethane ndi zinthu zosinthidwa ndi rabara zimapezeka m'malo osiyanasiyana ogwiritsira ntchito popereka zinthu zosiyanasiyana. Komanso, ma membrane, zokutira, mastic ndi sealant amapezeka. Zogulitsa zonse zimagwira ntchito yomatira kwambiri, kukhazikika, kugwira ntchito kwanthawi yayitali komanso kukhazikika, kukana kwa ma abrasion, kugwiritsa ntchito mosavuta komanso zachuma.

Kuti mudziwe zambiri za zida zina zotchingira madzi komanso zotchingira madzi phula, mutha kuyang'ana zomwe zili patsamba lathu.Zida Zoletsa Madzi Ndi Chiyani: Mitundu Yonse, Kagwiritsidwe Ntchito Ndi Zomwe Zilipo.
