Posankha phula ndi zinthu za lamba wa pulasitiki wokhazikika, tiyenera kuganizira zinthu zingapo kuti zitsimikizire kuti ikugwirizana ndi zofunikira zinazake. Nawa kalozera watsatanetsatane wosankha:
I. Kusankhidwa kwa Pitch
Pitch imatanthawuza mtunda wapakati pa ma module awiri oyandikana pa lamba, omwe nthawi zambiri amawonetsedwa mu millimeters (mm). Posankha kamvekedwe ka mawu, mfundo zotsatirazi ziyenera kuganiziridwa:
Kukula ndi mawonekedwe a chinthu chomwe chiyenera kuperekedwa: Onetsetsani kuti phula la lamba wa mesh limatha kutengera chinthucho mokhazikika, kupewa kutsetsereka kapena kupendekeka panthawi yotumiza.
Kuthamanga ndi kukhazikika: Kukula kwa phula kungakhudze kukhazikika komanso kuthamanga kwa lamba wotumizira. Liwu lokulirapo likhoza kuwonjezera liwiro la kutumiza, koma limachepetsanso kukhazikika. Choncho, posankha kamvekedwe ka mawu, m’pofunika kupenda kugwirizana pakati pa liwiro ndi kukhazikika kwake.
Malinga ndi zomwe takumana nazo, mabwalo wamba akuphatikizapo 10.2mm, 12.7mm, 19.05mm, 25mm, 25.4mm, 27.2mm, 38.1mm, 50.8mm, 57.15mm, ndi zina zotero. Komabe, kusankhidwa kwa mamvekedwe enieni kuyenera kutsimikiziridwa kutengera momwe amagwiritsidwira ntchito.
II. Kusankha Zida
Zomwe zimapangidwa ndi lamba wa pulasitiki wokhazikika zimakhudza mwachindunji moyo wake wautumiki, mphamvu yonyamula katundu, komanso kukhazikika kwamankhwala. Posankha zinthu, mfundo zotsatirazi ziyenera kuganiziridwa:
Chilengedwe: Madera osiyanasiyana ali ndi zofunikira zosiyanasiyana pazakuthupi za lamba wa mesh. Mwachitsanzo, ngati lamba wa mauna ayenera kugwira ntchito kutentha kwambiri, chinyezi chachikulu kapena malo owononga, m'pofunika kusankha zinthu zomwe sizingagwirizane ndi kutentha, chinyezi ndi dzimbiri.
Kunyamula mphamvu: Zinthu ndi makulidwe a lamba wa mesh zimakhudza mphamvu yake yonyamula. Ngati mukufuna kunyamula zinthu zolemera, muyenera kusankha lamba wa mesh wokhala ndi zinthu zokulirapo komanso mphamvu zapamwamba.
Kukhazikika kwa Chemical: Lamba wa mesh amatha kukhudzana ndi mankhwala osiyanasiyana pakagwiritsidwe ntchito, monga zotsukira ndi mafuta. Choncho, m'pofunika kusankha chinthu chokhala ndi kukhazikika kwa mankhwala kuti muwonetsetse kuti lamba wa mauna sungawonongeke ndi kukokoloka kwa mankhwala.
Zida zodziwika bwino za lamba wa pulasitiki wa pulasitiki zimaphatikizapo PP (polypropylene), PE (polyethylene), POM (polyoxymethylene), NYLON (nayiloni), ndi zina zotero. Zidazi zili ndi makhalidwe awo, monga PP zinthu zomwe zimakhala ndi mankhwala apamwamba komanso kukana kutentha, ndi PE. zakuthupi ndi kukana kuzizira bwino ndi kukana kuvala. Posankha zida, ndikofunikira kudziwa molingana ndi zochitika zenizeni komanso zofunikira.
Mwachidule, kusankha kwa phula ndi zinthu za lamba wa pulasitiki wokhazikika kuyenera kutsimikiziridwa kutengera zochitika ndi zofunikira. Panthawi yosankha, tiyenera kuganizira zinthu monga kukula ndi mawonekedwe a chinthucho, kutumizira liwiro ndi kukhazikika, malo ogwiritsira ntchito, mphamvu ya katundu, ndi kukhazikika kwa mankhwala kuti tiwonetsetse kuti lamba wa mesh wosankhidwayo ukhoza kukwaniritsa zofunikira zenizeni.
