Michina yekuboora nekugaya maPCB zvishandiso zvakakosha zvikuru mukugadzira mabhodhi edunhu akadhindwa (PCBs). Chimwe chezvinhu zvakakosha zvemichina iyi kushandisa granite, iyo inopa nzvimbo yakagadzikana uye inogara kwenguva refu yekuboora nekugaya. Zvisinei, pane zviitiko apo granite ingasavepo kana kuti mugadziri angasada kuishandisa.
Muzviitiko zvakadaro, kune zvimwe zvinhu zvinogona kushandiswa, zvakaita searuminiyamu, simbi yakakandwa, nesimbi. Zvinhu izvi zvakajairika muindasitiri yekugadzira uye zvakashandiswa sechinotsiva granite mukushandiswa kwakasiyana-siyana.
Aruminiyamu inzvimbo yakanaka kwazvo panzvimbo pegranite, uye yakareruka, izvo zvinoita kuti zvive nyore kufamba-famba. Yakachipawo zvishoma kana tichienzanisa negranite, zvichiita kuti ive nyore kuishandisa kune vagadziri vanoda kuderedza mitengo. Kupisa kwayo kushoma kunoita kuti isanyanya kusangana nematambudziko ekupisa panguva yekuboorwa nekugayiwa.
Chimwe chinhu chakakodzera isimbi yakakandwa, inova ndiyo inonyanya kushandiswa pakugadzira zvishandiso zvemuchina. Simbi yakakandwa yakasimba zvikuru, uye ine hunhu hwakanaka hwekunyorovesa hunodzivirira kudedera panguva yekuboorwa nekugayiwa. Inochengetedzawo kupisa zvakanaka, zvichiita kuti ive yakakodzera kushanda nekukurumidza.
Simbi chimwe chinhu chinogona kushandiswa panzvimbo pegranite. Yakasimba, inogara kwenguva refu, uye inopa kugadzikana kwakanaka panguva yekuchera nekugaya. Kufambiswa kwayo kwekupisa kunorumbidzwawo, zvinoreva kuti inogona kutamisa kupisa kubva pamuchina, zvichideredza mikana yekupisa zvakanyanya.
Zvakakosha kutaura kuti kunyange zvazvo paine zvimwe zvinhu zvinogona kutsiva granite mumichina yekuboora nekugaya yePCB, chinhu chimwe nechimwe chine zvachinobatsira nezvachinokanganisa. Saka, sarudzo yezvinhu zvekushandisa inozoenderana nezvinodiwa nemugadziri.
Mukupedzisa, michina yekuboora nekugaya maPCB zvishandiso zvakakosha mukugadzira mabhodhi edunhu akadhindwa, uye inofanira kunge iine zvinhu zvakagadzikana uye zvinogara kwenguva refu. Granite ndiyo yagara iri chinhu chinoshandiswa, asi kune zvimwe zvinhu zvinotsiva zvakaita searuminiyamu, simbi yakakandwa, uye simbi zvinogona kupa mabhenefiti akafanana. Vagadziri vanogona kusarudza chinhu chakakodzera zvakanyanya zvichienderana nezvavanoda uye bhajeti ravo.
