Yintoni i-polymer ngomnye wemibuzo ebuzwa rhoqo ngabantu abaninzi abajongene neekhemikhali zokwakha. I-polymer, exhaphake kakhulu kwizixhobo zokwakha, ikwaqukwa kwisakhiwo seemveliso ezininzi ezisetyenziswa kubomi bemihla ngemihla. I-polymer, eneentlobo ezimbini ezahlukeneyo njengezendalo kunye nezokwenziwa, ikwafumaneka nakwi-DNA yethu.

NjengokoUBaumerk, ingcali yeekhemikhali zokwakha, siza kuphendula umbuzo wokuba yintoni i-polymer kwinqaku lethu, ngelixa sichaza iindawo ezisetyenziswayo kunye nendlela ezisetyenziswa ngayo. Emva kokufunda inqaku lethu, uya kukwazi ukuqonda ukuba yintoni igalelo le-polymer, efumaneka kwizinto ezininzi ezisetyenziswa kwiprojekthi zokwakha, kwizakhiwo.

Ukuze ufumane ulwazi oluthe kratya malunga ne-mastic, esinye isixhobo sokwakha esisetyenziswa rhoqo, ungafunda inqaku lethu elinesihloko esithiYintoni iMastic? Isetyenziswa phi iMastic?

Yintoni iPolymer?

Impendulo yombuzo wokuba yintoni i-polymer njengentsingiselo yegama inganikwa njengodibaniso lwamagama esiLatini athi “poly” athetha uninzi kunye nelithi “mer” athetha iiyunithi eziphindaphindayo. I-polymer idla ngokusetyenziswa ngokufanayo neplastiki okanye i-resin kushishino lweekhemikhali zokwakha. Enyanisweni, i-polymer ibandakanya uluhlu lwezinto ezineempawu ezahlukeneyo. Zifumaneka kwizinto ezininzi zasekhaya ezisetyenziswa kubomi bemihla ngemihla, iimpahla, amathoyizi, kwaye okona kubaluleke kakhulu kwizinto zokwakha ezisetyenziselwa ukufudumala.

I-polymer yikhemikhali edityaniswe kunye kwiitsheyini ezinde neziphindaphindayo. Ngenxa yesakhiwo sazo, ii-polymer zineempawu ezikhethekileyo ezinokulungiswa kwiindlela ezahlukeneyo zokusetyenziswa. Ii-polymer zahlulwe zibe ziintlobo ezimbini: zendalo nezenziweyo. Irabha, umzekelo, yinto yendalo ye-polymeric esetyenzisiweyo kangangeminyaka engamawaka. Ineempawu ezibalaseleyo zokuthamba ngenxa yetsheyini ye-polymer ye-molecular eyenziwe yindalo.

Eyona polymer yendalo ifumaneka kakhulu eMhlabeni yi-cellulose, i-organic compound efumaneka kwiindonga zeeseli zezityalo. I-Cellulose idla ngokusetyenziswa ekuveliseni izinto ezifana neemveliso zephepha kunye neempahla. Ii-polymer ezenziwe ngabantu okanye ezenziwe ngokwenziwa ziquka izinto ezifanai-polyethylenekunye ne-polystyrene, iiplastiki ezixhaphakileyo ehlabathini, ezifumaneka kwiimveliso ezininzi. Ezinye ii-polymers zokwenziwa ziyaguquguquka, ngelixa ezinye zinesakhiwo esiqinileyo esihlala sihleli.

Zithini iimpawu zeePolymers?

Ukusebenza kwezinto eziqinisa ukuqina kwiprojekthi zokwakha kubaluleke kakhulu. Izinto ezisetyenziswa kwiikhemikhali ezandisa ubomi bezakhiwo kwaye zenze iindawo zokuhlala zibe mnandi nazo mazibe kwinqanaba elaneleyo. Ke ngoko, izinto zepolymer zibonakala zihlukile ngeempawu ezahlukeneyo. Iipolymers ezinokuveliswa kwindawo yeekhemikhali zinokuba neempawu ezifunekayo kuxhomekeke kwindawo ezisetyenziswa kuyo.

Ngenxa yezi mpawu, iipolymers ziyamelana neempembelelo ezinzima ezinokufunyanwa xa zisetyenziswa kwaye zibe phakathi kwezona ndlela zifanelekileyo zokuvelisa iikhemikhali zokwakha. Ngenxa yoko, izixhobo zokwakha ezisekelwe kwipolymers ezimelana namanzi kunye neekhemikhali zithandwa kakhulu.

Ziziphi iintlobo zeePolymers?

Ukongeza kwimibuzo yokuba yintoni i-polymer kwaye zithini iimpawu zayo, omnye umba obalulekileyo ekufuneka uphendulwe kukuba zeziphi iintlobo zee-polymer ezikhoyo kwimarike. Ii-polymer zahlulwe zibe ziiklasi ezimbini eziphambili: ii-thermoplastics, kunye nee-thermosets. Eyona nto ibalulekileyo eyenza umahluko phakathi kwezi ntlobo ze-polymer kukusabela kwazo xa zidibana nobushushu.

1. Iithermoplastics

Iithermoplastics yi-resin eqinileyo kubushushu begumbi kodwa iba yiplastiki kwaye ithambile xa ishushu. Emva kokuba zicutshungulwe, zihlala zisetyenziswa ngokufaka i-injection molding okanye ngokufutha, iithermoplastics zithatha imo yesikhunta apho zigalelwa khona njenge-melt kwaye ziqine zibe yimo efunekayo ngokuzipholisa. Inkalo ebalulekileyo yethermoplastics kukuba zinokuguqulwa, zifudunyezwe, zinyibilikiswe, kwaye ziphinde zibunjwe.

Nangona iipolymers ze-thermoplastic zibonelela ngeenzuzo ezifana namandla aphezulu okuchaphazela, ukuguquguquka, amandla okutshintsha imo, kunye nokumelana neekhemikhali, zikwanazo neengxaki ezifana nokuthambisa nokunyibilika kumaqondo obushushu aphantsi.

2. Iithermosethi

Umahluko ophambili phakathi kwee-thermoset kunye nee-thermoplastic polymers yindlela ezisabela ngayo kubushushu. Ii-thermoplastic polymers zithamba ngobushushu kwaye ziguquke zibe yimo yolwelo. Inkqubo yokunyanga ke ngoko iyakwazi ukutshintshwa, oko kuthetha ukuba zinokubunjwa kwakhona kwaye ziphinde zisetyenziswe. Xa zibekwe kwi-mold kwaye zifudunyezwe, i-thermoset iyaqina kwimo echaziweyo, kodwa le nkqubo yokuqina ibandakanya ukwakheka kweebhondi ezithile ezibizwa ngokuba zii-cross-links, ezibamba iimolekyuli endaweni yazo kwaye zitshintshe uhlobo olusisiseko lwezinto.

Ngamanye amazwi, ii-thermoset polymers zinesakhiwo esizithintelayo ekunyibilikeni nasekubunjweni kwakhona ngelixa zinyibilika. Emva kokunyibilika, zigcina imo yazo phantsi kobushushu kwaye zihlala ziqinile. Ii-thermosetting polymers ziyakwazi ukumelana namaqondo obushushu aphezulu, zizinzile ngobukhulu, kwaye azinakutshintshwa okanye zilungiswe.

Iindawo zokusetyenziswa kwePolymer

Izinto ezininzi ezenziwe ngokwenziwa kunye nezinto eziphilayo, kuquka iiplastiki, iirabha, izincamathelisi, izincamathelisi, amagwebu, iipeyinti, kunye nezitywini, zisekelwe kwiipolymers. Iindlela ezisetyenziswa kakhulu ziipolymers ekwakheni ziquka iipeyinti, iimembrane zokuthintela amanzi, izitywini, uphahla kunye neengubo zomgangatho, kunye nazo zonke iintlobo zezinto esinokuzicinga.

Njengoko kuphuhliswa amawaka eepolymers kwimarike kwindawo yelabhoratri, iimveliso ezisetyenziselwa usetyenziso olutsha zihlala zisanda. Iipolymers, ezifumaneka phantse kuzo zonke izinto ezisekhaya, zisebenza kakhulu ekuthinteleni amanzi. Izixhobo zokukhusela ezisekelwe kwipolymers, ezinokusetyenziswa kwiindawo ezahlukeneyo ezifana nekhonkrithi, intsimbi, i-aluminium, umthi, kunye nezigqubuthelo zebitumen, zigcina ukusebenza kwazo nokuba kumaqondo obushushu aphantsi, kwaye zinokumelana okuphezulu kwe-asidi kunye nesiseko, ziphakathi kwezinto ezifunekayo kwiiprojekthi zokwakha.

Ungazisebenzisa njani izinto zokukhusela ezisekwe kwiPolymer?

Izinto zokukhusela ezisekelwe kwi-polymer zinikezelwa yiBaumerk kwiintlobo ezahlukeneyo. Ukusetyenziswa kwezinto ezinikezelwa njengesigqubuthelo kunye nolwelo kwenziwa ngokwahlukileyo.

Eyona ngongoma ibalulekileyo ekufuneka iqwalaselwe xa ufaka isiceloI-SBS Modified, i-Bituminous Waterproofing Membranekukuba indawo yokufaka isicelo mayingabi naluthuli okanye ukungcola. Ukuba kukho iziphene kumphezulu, ziyalungiswa nge-mortar. Emva koko, i-polymer based bituminous cover ibekwa kwi-membrane primer ebekwe kumphezulu ize inamathele kumphezulu kusetyenziswa ilangatye letotshi.

Xa ufaka isiceloI-HYBRID 120okanyeI-HYBRID 115, umphezulu uyacocwa kuzo zonke izinto kwaye imifantu iyagudiswa. Emva koko, iimveliso, esele zilungele ukusetyenziswa, zifakwa kumphezulu zibe ziingubo ezimbini kusetyenziswa ibrashi, irola okanye isibhamu sokutshiza.

I-SUPER TACK 290, enye imveliso esekwe kwi-polymer kwikhathalogu yemveliso yeBaumerk, isetyenziselwa ukubopha iitheyiphu zokumisa amanzi kumphezulu. Ngenxa yokusebenza kwayo okugqwesileyo kokuncamathela, ibonelela ngokusebenza okufanayo ixesha elide kwiindawo apho isetyenziswa khona. Njengakwezinye izinto, umphezulu kufuneka ucocwe ngokupheleleyo kukungcola nothuli ngaphambi kokuba usetyenziswe. Emva koko i-SUPER TACK 290 isetyenziswa ngokuthe nkqo nangokuthe tye kwisithuba se-10-15 cm ukuvumela ukuba umoya udlule. Okokugqibela, izinto eziza kunamathela zifakwa ngokufaka uxinzelelo oluncinci ukuze ubukhulu be-adhesive bube yi-2-3 mm ubuncinane.
