Nhau - PPGI steel coil: mavambo nekuvandudzwa kwe color coil yakafukidzwa nemavara

PPGI simbi coilisimbi yakagadzirwa nesimbi yakaputirwa nejira rezvigadzirwa zvekuputira zveorganic, nekuda kwehunhu hwayo hwakanaka hwekudzivirira ngura, kutsungirira mamiriro ekunze uye chitarisiko chakanaka, inoshandiswa zvakanyanya mukuvaka, midziyo yemumba, mota nedzimwe nzvimbo dzeindasitiri. Nhoroondo yemarongero akaputirwa nemavara inotangira pakutanga kwezana remakore rechi20 uye pakutanga yakagadzirwa kugadzirisa dambudziko rengura yemaplate esimbi akaputirwa munzvimbo dzakanyorova. Nekukura kwetekinoroji yekuisa magirazi, simbi yakaputirwa yakashandiswa zvakanyanya mumusika.

Muma1960, pfungwa yemipumburu yakaputirwa nemavarayakatanga kuoneka, uye vagadziri vakashandisa tekinoroji yekuputira kuti vawedzere ruvara nezvikamu zvekudzivirira kumaplate esimbi akarukwa, zvichizadzisa zvinodiwa zviviri zvemusika zvekunaka uye kugara kwenguva refu. Munguva iyi, machira makuru anoshandiswa anonyanya kushandiswa nemafuta, kunyangwe aine zvakanakira pakushanda, asi kuchengetedzwa kwezvakatipoteredza nekuchengetedzwa kuchiri kuda kuvandudzwa.

Mumakore ekuma1970 nekuma1980, nekufambira mberi kwetekinoroji yekugadzira resin uye coating, maitiro ekugadzira ePPGI airamba achivandudzwa, kunamira, kuramba ngura uye kuramba kwe coating kwakawedzerwa zvakanyanya, uye mavara akasiyana-siyana uye magadzirirwo e coating akaonekwa pamusika kuti agutse zvinodiwa nevatengi vakasiyana. Munguva iyi, PPGI yakatanga kushandiswa zvakanyanya mukuvaka matenga nemadziro, ichiva chikamu chakakosha chezvivakwa zvemazuva ano.

Mushure mekupinda muzana remakore rechi21, kusimudzirwa kweruzivo rwezvakatipoteredza pasi rose kwakaita kuti indasitiri yependi ikure nenzira yekudzivirira girini nezvakatipoteredza. Vagadziri vazhinji vari kutanga kushandisa machira ekudzivirira anobva mumvura uye machira asina kugadzirwa kuti vaderedze kukanganisa kwavo zvakatipoteredza. Kuchinja uku hakungogadzirisi kuchengetedzeka kwePPGI chete, asiwo kunoita kuti ive nemakwikwi akawanda mumusika. Panguva ino, nzvimbo yekushandisa yePPGI yakawedzerwa kuti isanganisire maindasitiri mazhinji akadai semidziyo yemumba nemidziyo yemukati yemotokari, zvichiratidza kunaka kwayo mukusiyana-siyana uye kuchinjika.

Nekufambira mberi kuri kuramba kuchiitwa nesainzi netekinoroji, mikana yekuvandudza PPGI mune ramangwana yakakura. Kuunzwa kwezvinhu zvitsva netekinoroji kuchasundidzira PPGI kumabasa akakwirira uye budiriro isingakuvadzi nharaunda. Nekusimbiswa kuri kuwedzera kwekuvaka kwakasimba uye dhizaini yegirinhi, PPGI inotarisirwa kuita basa guru munzvimbo idzi.

Muchidimbu,Mipumburu yakafukidzwa nemavara ePPGIzvave chinhu chakakosha muindasitiri yemazuva ano nekuda kwehunhu hwazvo hwakanaka uye chitarisiko chakanaka. Nekufambira mberi kuri kuita tekinoroji uye shanduko mukudiwa kwemusika, kushandiswa kwePPGI kucharamba kuchikura, zvichiunza mikana yakawanda kumarudzi ese ehupenyu.
