Kukonza, kumaliza ntchito kapena zomangamanga - Mau awa onse nthawi zonse amagwirizanitsidwa osati kokha kukonzanso malo okhala, komanso ndi zinyalala zambiri. Nthawi zina pali zambiri moti ngakhale nthawi zambiri malingalirowa amalepheretsa chilakolako choyamba kusintha kunyumba. Komabe, kulengedwa kwa chinthu chophweka ngati matumba kumanga zowonongeka kumathandiza kwambiri. Tiyeni tione mitundu yawo yofunikira, komanso tidzakambirana mwatsatanetsatane zoyenera kusankha.
Zida za zikwama zowonongeka
Ndipotu, zikwama zomwe zinkafuna kuti zinyalala zisamangidwe zikufanana kwambiri ndi zikwama zamagazi zomwe timadziŵa. Kusiyana kwakukulu ndi kukula kwakukulu ndi zinthu. Ngati zikwama zapakhomo zimapangidwa ndi mphamvu zopanda mphamvu za polyethylene ndipo zimakhala ndi mlingo wokwanira wa malita 60, zimamveka kuti zowonongeka zogwirira ntchito sizingathetsedwe.
Zikwama zogwirira ntchito zowonongeka zikusiyana ndi kuchulukitsitsa kwawo ndi kukula kwake. Zimapangidwa ndi zipangizo ziwiri - polypropylene ndi polyethylene. Zoterezi zimakhala zosiyana ndi zomwe zimagwiritsidwa ntchito popanga zikwama zapakhomo. Pulothilini yotereyi imapangidwa pansi pamtunda wochepa. Chikwama cha polyethylene chapamwamba kwambiri chimatetezeka ndipo chimatsutsana bwino. Zoterezi zimakhala zosavuta kuzindikira ndi kuwala, kunyezimira komanso kusowa. Matumba a polyethylene omwe amalembedwa ndizitsulo amadziwika kuti ndi amphamvu komanso owopsa. Panthaŵi imodzimodziyo amatha kutambasula mosavuta ndi kuwonongeka mosavuta ndi mapeto ake. Dziwani kuti mankhwala oterewa ndi osavuta pa matte pamwamba ndipo amalembedwa dzimbiri.
Mitundu ina ya matumba amphamvu a zomangamanga zimapangidwa kuchokera ku polypropylene yachiwiri. Matumba amenewa amatha kulimbana ndi katundu wolemetsa, kawirikawiri amadula kuchokera kumphepete mwazitali ndipo osapyola. Mwa njirayi, matumba amenewa sagwiritsidwa ntchito kokha chifukwa cha kutayidwa kwa zinyalala, komanso kusungirako zakudya - zakudya, shuga. Kawirikawiri, matumba a polypropylene amapangidwa ndi ulusi, motero amakhala ndi nsalu.
Kodi mungasankhe bwanji zikwama zopanga zinyalala?
Mukamagula zikwama zabwino zogwirira ntchito, muyenera kuganizira mfundo zingapo. Choyamba, ndilo buku la thumba la zomangamanga. Izi ndizofunikira zogwira ntchito zosiyanasiyana. Kawirikawiri "yaying'ono" - 90 malita, 120 malita ndi 180 malita. Matumba akuluakulu a zomangamanga akhoza kufika 200 malita, 240 malita ndi 350 malita.
Kutenga katundu ndi katundu wina wofunikira. Pazitsulo zing'onozing'ono zomanga zomangamanga zoyenera zikwama za polyethylene. Zamagetsi zimatha mosavuta kulemera kwa makilogalamu 40. Pofuna kuti musamalipire ndalama zowonjezera, mugule matumba odulidwa kuti mumange zitsamba zobiriwira. Matumba akuluakulu amapangidwa kuchokera ku pulayimale ndi sekondale polypropylene, choncho amawononga pang'ono, koma amatha kupirira makilogalamu 65. Nthawi zambiri amanyamula zonyansa zotere monga njerwa zowonongeka, zinthu zowonongeka ndi simenti. Matumba achizungu a pulasitiki oyambirira amaonedwa kuti ndi okwera mtengo kwambiri, chifukwa amafunidwa kuti asungidwe chakudya. Ngati mukufuna kabokosi kameneka, sankhani mankhwala a polypropylene ndi kanema. Ngati tikulankhula za kuchuluka kwake, ndiye chizindikiro ichi cha thumba la polypropylene chimasiyana ndi 50 mpaka 115 g pa mita imodzi. Ngakhale kulipira, matumba a polypropylene amalipiritsa, chifukwa amawonekeratu kuti ndi othandiza.
Kwa zitsamba zing'onozing'ono, mungathe kugula zinthu zochepa zogwiritsidwa ntchito zopangidwa ndi polyethylene matumba. Mwa njira, mawonekedwe a filimuyi - imodzi mwa zinthu zofunika kwambiri posankha thumba la zinthu zoterezi. Amakhala ndi microns 20 mpaka 70.
