Mumvuri wematende emumaindasitiri unoshandiswa mumaindasitiri kudzivirira zvinhu zvakagadzirwa nemaindasitiri kubva kumamiriro ekunze nehunyoro kuti zvisaparare nengura. Zvinobatsirawo pakutakura mabasa edu emaindasitiri nekuisa mumvuri mumaworkshop.
Tarpaulin kana tarp ipepa guru rine zvinhu zvakasimba, zvinochinjika, zvisingapindi mvura kana kuti zvisingapindi mvura, rinowanzova jira rakaita secanvas kana polyester rakaputirwa nepolyurethane, kana rakagadzirwa nemapurasitiki akadai sepolythylene. Tarpaulin inowanzova nemagrommets akasimbiswa pamakona uye pamativi kuti agadzire nzvimbo dzekubatanidza tambo, zvichiita kuti dzikwanise kusungirirwa pasi kana kusungirirwa.
Matende emazuva ano asingadhuri anogadzirwa nepolyethylene yakarukwa; chinhu ichi chinobatanidzwa nematende zvekuti chave kuzivikanwa nevanhu vakawanda sepolytarp.
Matende anoshandiswa nenzira dzakawanda kudzivirira vanhu nezvinhu kubva kumhepo, mvura, uye chiedza chezuva. Anoshandiswa panguva yekuvaka kana mushure menjodzi kudzivirira zvivakwa zvakavakwa zvishoma kana zvakakuvara, kudzivirira nyonganyonga panguva yekupenda nezvimwe zviitiko zvakafanana, uye kuchengetedza nekuunganidza marara. Anoshandiswa kudzivirira mitoro yakawanda yemotokari dzakavhurika, kuchengetedza mirwi yehuni yakaoma, uye nzvimbo dzekugara dzakadai sematende kana zvimwe zvivakwa zvenguva pfupi.
Taravhani yakaboorwa
Matende anoshandiswawo pakudhinda zviziviso, kunyanya pamabhodhi ekushambadzira. Matende ane maburi anowanzo shandiswa pakushambadzira kwepakati kusvika kukuru, kana kudzivirira mascaffolding; chinangwa chekuboorwa (kubva pa20% kusvika 70%) ndechekuderedza kukanganiswa nemhepo.
Matara epolyethylene aratidzawo kuva nzvimbo inozivikanwa kana panodiwa jira risingadhuri uye risingapindi mvura. Vavaki vazhinji vematara eplywood vanoshandisa matara epolyethylene pakugadzira maseiri avo, sezvo asingadhuri uye ari nyore kushandisa. Nemhando yakakodzera yetepi yekunamira, zvinokwanisika kugadzira maseiri anoshanda echikepe chidiki chisina kusona.
Dzimwe nguva matende epurasitiki anoshandiswa sezvinhu zvekuvaka munharaunda dzevagari vekuNorth America. Matende akagadzirwa nematende anozivikanwa sematende.
Tarapulin yepolythylene ("polytarp") haisi jira rechinyakare, asi, laminate yakagadzirwa nejira rakarukwa uye jira. Pakati payo pakagadzirwa nezvidimbu zvepurasitiki yepolyethylene, nemapepa ejira rimwe chete akabatanidzwa pamusoro. Izvi zvinogadzira chinhu chakafanana nejira chinodzivirira kutambanudza zvakanaka kumativi ese uye hachipindi mvura. Mapepa anogona kunge ari epolyethylene yakaderera (LDPE) kana kuti high density polyethylene (HDPE). Kana akabatwa nechiedza cheultraviolet, matarapulin aya anogona kugara kwemakore akasvikwa nemhepo, asi zvinhu zvisina UV zvakagadziriswa zvinokurumidza kupwanyika uye kurasikirwa nesimba uye kudzivirira mvura kana zvikasvikwa nechiedza chezuva.
Tinogara tichitsvaga vadyidzani vatsva vanoda kuongorora zvigadzirwa zvedu uye kugadzira chimwe chinhu chitsva pamwe chete. Makambani edu ekugadzira anogona kushandiswa mumabasa akasiyana-siyana.
